Rachel: I'm in love with Finn..
Kurt: Oh, it's on bitches.

Anon: I be a noob who don't ship monfer! Herp derp.
Monfer shippers: Oh, it's on bitches.

Get the Oh Shit Bitch mug.
An exclamation of surprise, either used in a defeated manner, or in a manner of pride. In many cases the H in the Oh can be drawn out for effect; for example: "Ohhhhhhhhh BITCH i just spanked yo monkey ass!"
Defeated Manner: "Oh Bitch! I just got my ass kicked! *Starts crying*, "

Manner of Pride: "Oh Bitch! Someone just got MOLLYWHOPPED!"
