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!"

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.
