Okay so everybody pretty much knows what a bro is, but what do you call girls who act like bros and wear sperrys and rock nantucket reds?? A brosis. It's not some boil or sore dont worry. Its just a girl who acts like a bro.

A BroSis describes girls who wear sperrys, rock nantucket reds, throw lax around with a boys stick, rock lax t-shirts, and able to party like a bro.

brosis 

The California-born, politically correct alternative to and/or replacement for the word "bro". Although the target of reference is usually female, it is perfectly acceptable to address a subject of any or unknown gender, as the word itself is unisexual and non-descriminatory vs male, female, or other.

1.
"It ain't no bro; it ain't no sista; it's'a brosis, brosis!"

2.
Man: "Dude, man, brosis, that ass is 'hella dank'. I'd hit it like an abusive husband."
Response from woman or subject of unknown gender: "Fuck you, pig! But I appreciate the fact that you did not call me bro, my bro."

brosis 

the desease of being a 'bro'. When you're such a 'bro' and think you're so rad (high fives all around) that regular people feel smothered in your ego and attitude. Most guys catch brosis around 17 and dont loose it until about 23.
Common symptoms are thinking you're rad, clowning on everyone else, refering to everyone as 'bro', and always talking smack about bitches and getting laid.

That guy had total brosis.

There's way too much brosis in that crew for me to handle.

Leave your brosis at home and come have fun with us.

You can’t use male pronouns for Jake anymore. He’s going through brosis and prefers using a female pronoun.
