Get the BMM mug.

BMM

A failure to thrive...a loser to society..a lost cause...imbecile which if you're reading this Maggie and Mackenzie and Brittney Spears it means a stupid person. Sad face times infinity& no beyond. Mean girls, fake friends, no souls and a menace to society. P.s. if you are reading this don't go on a boat with these three girls bc they're unprepared and will most likely push you off the boat and won't give you a life raft. If they even packed it. To be continued.Evil people suck forever. Ewwwwwww

BMM is When someone is a failure and hands are too nasty to hand anything to, especially a crown.
