My biggest pet peeve is lack or respect.  I find it such a turn-off when a person violates your opinion, body, etc.

Typically, Laughing Out Loud. If you think it's annoying, you're not the only one.

My pet peeve is people who will say something without thinking about what they're really saying. Example: I'm washing dishes and someone comes in the room and says "Hey, what are you doing?" to which I'll reply "brushing my F**king teeth!" I hate it when people don't think before they speak.

I deal with in two ways the first is I bought an illegal, (please don't call the police on me), cell phone jammer off of ebay, I bring to the movies and restraunts...usually wait til they get obnoxious and then turn it on.  Second I start using the same names and pharse they are using for example: I hear them say Susie was so drunk, I turn to my dinner partner and loudly proclaim about how  Susie was naked and dancing on the table last night.  Seems to get even the most obnoxious ones to tone it down.

You've several excellent answers already, zen (including your own example, which I too detest). But, in addition to some others previously mentioned, I think the one I really can't stand (which has not yet been posted) is the usage of "party" as a verb. I don't know why, precisely, but I have always loathed this expression and never use it myself. It reeks of pseudo-trendy hipster-loser status and thus makes me deeply nauseous. Please, if you ever hear or see me employ this term (not in a completely sarcastic context, that is), shoot me. Do not hesitate. Do not equivocate. Do not pass Go. Do not collect $200. Do not -- you get the idea. ;)
