no it isn't because you use your calf mucles not your knees. might get a little sore the next day though o and about the grindy sound you hear from your knees, i get it too and it means nothing it is just a little friction between your joints

Rolling on floor laughing \n\n\nMy guess is that it comes from ROFLCOPTER\n\n\n\n\n\n"ROFL Copter is when someone is sitting on a computer chair, such as the one i am in right now, that rotates about at the stem. A ROFL Copter is when you laugh so hard, you actually spin out of the chair.\n\nOMG, I found this flash toon, and I ROFL coptered."

"The origins of this gesture are highly speculative, but is quite possibly up to 2500 years old. It is identified as the digitus impudicus ('impudent finger') in Ancient Roman writings and reference is made to using the finger in the Ancient Greek comedy The Clouds by Aristophanes. It was defined there as a gesture intended to insult another. It has been noted that the gesture resembles an erect penis."

you laugh out loud because someone played a frank on you and you just learned that someone tricked you.  you want to do that to other persons to have "revenge".

Because humour where people get hurt (but not badly) is still the funniest. It's visual and it's universal. Think of how your friends laugh when you fall over (or you at them) as long as they don't injure themselves.

Probably compensation for an unnatural move...it doesn't feel right, so your body tries to compensate for it.

Because it's FUNNY. Go along with it even if you are embarrased. Be the good-natured person.

the shank is the part of the leg between the knee and the ankle.\n\n'longshanks' is a rather old-fashioned way of teasing someone for being tall (in more modern english tall people are called 'lofty').

The name "funny bone" derives from the fact that the bone in your upper arm, the humerus, is a homophone of the word "humorous".  When you "hit your funny bone", you get a sensation that is not funny at all...IT HURTS!  At the distal end of the humerus (basically, the part of the bone that lies at the elbow joint) there is a nerve called the ULNAR NERVE which runs in a shallow "valley" within the humerus itself.  This landmark is called the "groove for the ulnar nerve" on the humerus.  Sometimes this nerve can be pinched upon the bony parts that surround it, and when it does you get the sensation of pain.  You  should be aware that the ulnar nerve provides the sensation of touch from the pinky finger and half of the ring finger, so when you HIT the nerve (as something strikes the elbow in the exact location of the nerve) you "feel" the pain in these two fingers.  OUCH!!!!\n\nHope this explanation helps!

Yes, I've heard of situations like that...The bruises are from that dang knee cap sliding. It's moving around, causing bruises that start from the inside and work their way out. I don't think that normally bruises start from the inside out unless you have a problem like yours, though.

No, you're not thick.  I was the same way and had to ask.  It stands for Laughing My A** Off

It is the child equivalent of get stuffed. If someone pokes there tongue they are basically disrespecting you. Usually a quick slap under the jaw will end that habit.
