Biby 

A short fucking bitch with daddy issues and a heart too big for her own good. She's dumb and kinda slow but she's also a good listener with a milf bod. She takes a while to understand logical things but is really emotionally intelligent. She's a good friend but i hate her and she's dumb and stupid and kinda dull brained. She has big tits tho.

"Damn that girl is hot asf"

"Don't bother, she's biby."

Bibye bump 

When two bro's (usually frat boys) reach between their legs to give bumps. Bibye bumps are usually reserved for saying farewell to your most intimate of bros. Bibye bumps can be done back to back, front to front, or back to front.

Yo bro, have fun at Mtv spring break. Now give me a Bibye bump.
