His penis was so large, he ripped my boim.

BOIM 

The moment when, in the British TV show Doctor Who, a new person first enters the TARDIS and realizes it is bigger on the inside. A BOIM stands for a Bigger On the Inside Moment. BOIM's are usually accompanied by running around the TARDIS, and gaping.

"Whoa did you see Rory's BOIM last saturday?"
"Yeah it was hilarious!"

boim 

The taste of a girl's pussy when she either is too-close to her period or peed recently.

Sheri always seems to taste like fucking boim, what a sloppy cunt she's got.

Boimcee

1.) When you are white and think you are black. Otherwise known as a wigger

2.) Also a condition to where you cant talk or shit due to sticking too many dicks down your throat and up your ass.

3.) When you have a dick that looks like a vagina due to taking steroids and you are also extremely short due to the steroids. Yet you dont get results from them you still are weak.

4.) When you have a jealousy disorder and have to put things on urban dictionary to make yourself feel tough. You arent good at anything and are jealous of those who are good.

NOTE: If there are any other definitions i forgot feel free to define people those are just what I have heard over time

Matt cant talk because he is so boimcee right now those dicks are catching up to his gay ass.
