SUMB is an abbreviation for Super Ultimate Mother Bitch. It refers to the leader of the bitchhood. Typically, the SUMB is beyond bitchy and is known for flirting with guys.
What!? Mandy is a SUMB? No wonder she is so ugly and mean yet always tries to flirt with guys. She is beyond cheap and disgusting.
