A.k.a. The MBC. A type of sexual revenge for a woman. A man and a woman are having sex and the woman is on top. Right when the man says he's getting close to finishing, the woman jumps off, throws Old Bay on his genitals, and immediately leaves. Now what the man didn't know is that the woman has crabs. So now he has blue balls and crabs, all covered in Old Bay, Maryland Style.
Man1: Yo, did you hear how she did him dirty?

Man2: Nah, what happened?

Man1: She got him with The MBC!

Man2: No way! Not The Maryland Blue Crab!
