I'm out like a... (most likely offensive)

I’m trying to think of as many good expressions for use while leaving. Offensive is fine (and encouraged).

I’m off like a prom dress.

I’m out like a slow kid in dodgeball.

I have to make like a fetus and head out.

I’m out like a dirty tampon.

Shoot me your best!

Eh? Speak up, sonny, I can’t hear so well. Did you say that the egregiously offensive stuff should be left to e-mail? Good, that’s what I thought you said.

well I didn’t mean DISTURBINGLY offensive, just slightly off-color. Message understood.
