A) someone who has a super long voicemail message...or you have to listen to a long stupid song before you can leave a message after the tone
B) listening to someone that is always bragging about this, that, or the other...when you know damn welll that they are lying. in other words, listening to a compulsive liar talk about nonsense all day.
C) having to see another damn question about "Am I pregnant?" or "How do I tell him/her that I like them?" on Y!A
D) seeing little kids that are running over their parents in the mall or grocery stores...when you know they need a good butt whipping instead of "reasoning with them"
E) someone that keeps coughing next you, without the courtesy of coving their damn mouths.
