SB

an acronym created by two teenage girls. originally named to mean "Spoiled Brat", but now can mean anything from "Splattered Brains" to "Shitty Bitch" to "Shi Bal". Refers to a certain girl whose initials are A.M.K, but can be used by anyone to name any similar poser-like bitch.

"There was that one time when SB dragged me on a date with her fat boyfriend and lied to her mom that I was with my 'boyfriend' too, OTL.
