When you compete to see who is the best sex partner. (Like a bake off, but with sex)
She's with that bitch?? I'll challenge her to a sex off and we'll see who's best in the sack.

Get the Sex off mug.
The act of leaving immediately after orgasm. Commonly occurs after bad sex.
I couldn't stand that skank from last night, but I guess she was worthy of Walk-off Sex.
