They are all phrases used for expression of surprise at something - all probably also used in old comic books a few decades ago (eg the Beano or the Dandy)

They are sort of a play on words, combined with a humorous attempt at replacing a swearword or blasphemy with something harmless.\n\nWhen you start to say "Oh my God!" you catch yourself at the 'g' and change it to "oh my Giddy aunt!"\n\nWith "God!" again you stop at the 'g' but change it to "Gordon Bennett!"\n\nAnd of course you might be about to say "F**king heck!" (or something similar,) when you sense your Grandmother breathing down your neck, so you catch yourself at the 'f' and say "Flipping Nora!"

Lol they dont know what it means until they are told what it means. Dont expect real answers.

*raises her hand*\n\nMe!\n\n---------\n\nOh well,.. it means things you are saying may take a turn for the grim, sick, twisted,.. undead,...   Not the kind of things that are like Sunshine, Lolipops, and Puppies,...  But maybe your laughing at someone getting hurt or your jokes contain such out come.\n\nIt may seem funny to you but not some thing other people notice,.. because they are busy being as much like the Average Joe as posible.

Blast from the past- it means up to mischief or " no good"  I do not know where it came from but it has been around since at least the 30-40's  \n\nI just googled shenanigans and it is from the 1920's and there actually was a play named that.  Try Wikipedia- but I am right about the meaning.

Shoo', lemme hit chu up with da coolbeenz infomation.\n\n- Cool kids make their sentences appear grammatically correct, or at least indicate they know how to use grammar by capitalizing the first letter of their sentence and ending it with a period.\n\n- Lol never really is acknowledged as the whole "laugh out loud" thing.. it's just indicating laughter in general. "Oh you're so funny. Lol." You can also say Lawl, Lollerskates, lool, kik. Don't ask why, people just assume those are kewl. Other forms of laughter can include "ROFL" Which is "rolling on the floor laughing" Or "LMAO" Which is "laughing my ass off". Could also always just say "Hehe" "haha". \n\n- Shortening words.. for example "Seriously" can either become "Srsly." Or "Serially." Again, don't ask why, people think it's kool.\n\n- Don't ask ASL anymore. ASL is so ghey. It means you're a horny bastard lookin' for some sorry cyb0rg seckz to give you more of a reason to touch yourself. Not cool. Just simply ask when you're curious.. "Oh, where do you live btw?" "And how old are you?" People tend to play it off as if those certain facts don't matter because they're not internet predators looking for cyb0rgz, but rather a nice conversation with whomever.\n\n- FTW. It's the newest acronym that I know of. I think it's pretty ghey, but other people like it. "For the win" is what it means. You usually say it after you've made a comment that defeats the previous comment relevant to topic. Say it's favorite cereal.. and someone says Froot loops.. you'd then proceed to say "Cinnamon Toast CRUNK, ftw." And thus.. you've pwned them.\n\n- Pwn is to "own" as in, defeat someone to silence.. usually when your witty remark has bested theirs. Pwning is something you should be proud of. How proud? As proud as someone could be for winning an intranet argument.\n\nThe rest is simply using the English language.. using too much internet lingo makes you look like a retard, so just stick to the above.\n\nOh.. don't forget the emotion icons.. or shall we say.. "Emoticons". =/, =), =D, =P, D=, and variations of eyes using colons ":" instead. Could also use more japanese-y ones ^-^ -_-; o_o ._. to name a few. Semi colons or apostrophes indicate some kind of sweat. Don't ask me why.\n\nTry not to get hooked onto emoticons though. I'm beginning to think they're lame although I can't stop using them.. and it sickens me to death.

These are stereotypes.  The saying asks us not to believe them.\n\nSeems simple enough to me!

this is a bunch of medical words that are put together.  In the string they are in here, they don't mean anything.  If this were in the middle of a sentace, it might have meaning.

It was a complete mystery to me for a while, & I didn't think to look it up. I have one friend who uses it all the time in text messages - so much that it's driven me a little crazy. For him it means "laugh out loud." I've heard other people say, "lot's of laughs," but that sounds a little hokey.\n\nThe thing that I like best about it - well, the only thing mildly amusing, to me at least - is that "lol" looks like an open mouth between the sides of a face, like someone saying, "OH!"\n\nStill, I wish it would disappear so I wouldn't have to be crazy anymore.\n\nAll the best.

Because it was written so long ago that the meanings are cryptic to us - they were not as cryptic at the time - and at that time hidden meanings and innuendo were used a great deal in theater.  Remember, Shakespeare's plays were written to be performed on stage at the time.\n\nThese sites should give you plenty of information for your report.

They are short, pithy statements meant to illustrate a point.\nAlso called proverbs, axioms, mottoes.\n\nA stitch in time saves nine\n\nA penny saved is a penny earned\n\nEtc.\n\nThe examples you post are pretty weak aphorisms

I agree - it's the metal "decoration" you see in people's mouths (which, frankly, I think looks stupid...)\n\nIt can also mean to quiz or interrogate someone (ie - Why are you grilling me about where I was yesterday??)\n\nI've also occasionally used it heard to describe a woman's bust area (about as lovely a description as calling it a rack....)\n\nI would bet the song you heard was either meaning the metal in someones mouth or a woman's chest, or it was a play on words where they were going back and forth meaning both...

It's an onomatopeic expression used humorously to denote someone grumbling and ranting, and quite often to replace a bout of swearing with something more socially acceptable. It's quite old-fashioned, not really used anymore...

I think it means "you" haven't read it. If you go back read one that is bold, It probably won't be bold anymore, at least that's how the inbox works.

its funny, but only if told outloud. if you can see the different spelling, it either spoils the joke ormakes itnot work. audibly there is no difference so one is thinking about bear, when you really are saying bare. its sort of funny.
