RAB stands for ratarted ass bitch, so if someone is annoying just say, “your RAB” if they ask what it means just say, “ Ride A Bunny.

Stands for Rats Ass Build-up. The occurrence throughout the day, where remnants of poop/toilet paper/undercheese/etc. get collected between your ass checks to cause irritation or itchiness. Poorly wiping after stool, hemorrhoids, and lack of bathing are the leading causes.
Greenie- “Mike I’ve been walking all day and the RAB is killing me.”
Mike- “did you shower today? If not that’s why your ass itches!”
Greenie- “I showered two days ago”
