A hot and super sexy man with a 9 meter defeater. Has no fucks to give. He is very thicc and he has more dick inside of him than outside. All girls fall for him when he is in the same room.
Used often by pre-teen girls on twitter, "Mother Rumpin" is often used as a way of saying "mother fucking" or more literally "I'm scared to swear on twitter because my parents insist on following me." Often used while tweeting the pope, can be directly translated into latin as Mater Caudam. Girls who use this expression often have a liking for furry animals such as dogs.
