Hmm...for me, its jackasses that gloat about doing dumb stuff that anyone can do, people that order me around without any legitimate claims to do so, and people who touch or play with styrofoam or balloons. The last one is actually quite debilitation to me, as it cases me mental and physical distress. Like, really, Ive gone comatose from heaing someone playiwith foam for like 5 minutes :\
