No matter how verbiose and intelligent their argument. You come back with something to the effect of "put your mouth up to my mud volcano and wait you fat faggot" and you can see their face turn red and contort with feral aggression. They just spent all that time trying to convince you of something they believe is right in their heart and you insulted them like a five year old kid. You fucking win. The angriest one who punches a wall will not sleep tonight.
Last known use of poo-poo tactics was during a pro-choice argument with my sister, she is an educated bimbo but I was getting bored and wanted to watch the hilarious edited version of Casino on TBS. The argument was getting intense and the volume of voices was rising exponetially. We were even talking really fast and making hand gestures like two latin women. So I just simply said "speaking of abortion, you're alot fatter since I last saw you.." She slammed her hand down on the breakfast bar and said "oh that's just great" and stormed up the stairs. I made myself some fajitas and laughed at the movie.
I lost once when my uncle Rick showed me how to argue the right way. He's pretty stupid and buys happy meals still. But he made me so angry I just about threw my coke at him at Arby's. I learnt from the best.
