mother rumpin 

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.

@ThePope: I mother-rumped your dad when he was your age ;)
