when you're on an online chat site, like Omegle, or Chat Roulette, internet trolls will try to piss you off by denying the fact that you are a girl, if you really are a girl and call you a broshifter.
girl: i promise, i'm definitely a girl!

troll: no you're not bro, you wanna know why? cause you're a broshifter!
