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.

A slur used against a very specific group of people. Commonly confused with a large ass, many people do not know the true meaning of the world.
