Dumpy Bumpy 

Slang used to describe sexual activity involving oneself's anal cavity especially if the receiver is rather large from behind. Typically the posterior-end is referred to as "dumpy" which is due to roots within the word "Dumptruck" (which is a vehicle commonly used to haul large quantities of sediment from one location to another), and the word "bumpy" being used to describe the motion of anal sex where one bounces off of their partner.

Man! Me and your sister got it on last night. We did the dumpy bumpy so many times!

a girl who has a fist so far up her rectal orifice that the fister has full control over her body, making her a human ventriliquist dummy.

Getting tired of listening to Arryn bitch about how sore she was, I pulled my cock out of her ass, shoved my fist in there and made her bummy dummy dumbass say, "My anus is heinous."
