Why do you hate bros? lol
I don't know if it's any different where you live, but holy stuff
Bros here are the most unfunny, sarcastic, pompous pricks I've ever seen. The kinds of guys who say some stupid joke that nobody really finds funny, but all of his dumb friends laugh, and all of the little prissy cunts around him laugh at because he's some big hot shot. The kinds that wear Metal Mulisha shirts with khaki shorts, black skater shoes, and (usually) a black cap. The kind who make dumb jokes about anything they find stupid.
The ones here have a tendency to talk about nothing more than slutty to semi-slutty looking chicks, stupid jokes, ridiculously common drama (ie "he said this to my friend and now she's sad ;~;"), riding their dirt bikes and getting drunk at parties. I'd be fine with it if it wasn't so continuous, and said in such an arrogant tone. Unfortunately, it is, and so, I hate them.
