bra bro:
A superawesome, five-tool player in life. Comfortable enough with her feminine side to embrace her tomboy. Trendy yet timeless sense of style– like a minimalist with flare. Generally found in social settings, but enjoys bra’ing out alone. When solo, spends time making and doing cool things and then tweets about it. Always exploring- and learning from interesting people. Wears bras. Showers.

The most holy bond between two bros. Bro-trust is the faith that your bros will back you up and always keep their promises.
"Bro, promise to wake me up before you leave. I really want to come."
"I will dude."
"Promise on bro-trust."
"I will dude."
"Promise on bro-trust."

A seemingly slow college bro with a surprising amount of knowledge stored inside him. He doesn't acknowledge it, but brings it up when he feels that it's necessary.
Chad: yo that party was like, totally radical!
Adam: dude, doesn't that word have, like, negative connotations? If you're talking about a political party then that scentence could really be interpreted the wrong way, man.
Chad: wtf? You're such a book bro, man.
