B.I.D

Brony in Denial.

Some guy saying that my little pony is for little girls, but secretly loves it.

Person 1: Have you seen the new show, my little pony friendship is magic? Gosh it's so gay.

Person 2: Yeah man, I hate it.

After both guys get home, they quickly get behind their computer to watch my little pony friendship is magic.

In this scenario, both guys are B.I.D's.

B.I.D

B.I.D - bitch in disguise.

a B.I.D will act all friendly and pretend they are sweet and kind to everyone, but as soon as you piss one off, they show there true colours.

this can also be them being two faced.

your girlfriend moves to another country, you give it a while and tell her it's not gonna work, she flips out and does everything in her power to hurt you.

your friends with someone, and they say vindictive things about you to your other friend.

B.I.D. 

Bottom in Denial. Coined by the gay community, B.I.D. is a term referring to a person that is so clearly a bottom/has bottomed but claims to be a top, putting on the charade of toughness and dominance, when it so clearly is not the case.

Andrés: yeah, uhh, bro that wasn’t me I’m totally a top
Michael: yeah sure whatever B.I.D. we all know you bottomed for Reese.
