There are a lot of things that bother me (global warming, social injustices, Sarah Jessica Parker's face) but I absolutely can not fucking stand it when people uses the expression "360 degree turn". As in, "Oh, he stopped snorting coke off of that hooker's ass and went to priest school. Yeah, it was a real 360 degree turn for him."
You do not have to be a fucking geometry major to know that 360 degrees is a FUCKING CIRCLE!
If you did a 360, you would be right back where you fucking started!!!
That pisses me off so much.
