Stands for Insanely
Awesome Bitch,
something that describes the great gynecocynic cynophile M and her utter epitomeness of pulchritude and bitchitude; can be extended to any girl who can be both
awesome and a bitch at the same time, thus making them insanely entertaining.
It's what all of M's friends call her, and was first invented and used by the effulgent Zorbalicious.
"Every girl has an inner bitch,
mine's just not so inner,"
said the
crux of iabidity, the one and only M.
