A man who repeatedly enjoys the kind of women who have a huge ass, a.k.a. a dummper butt.

The type of ass that makes her look like a bowling pin with cellulite.
Tony: Dude, he went dumper diving last night, again!

John: He loves skinnies but never turns down a fatty, bro.

Tony: This is true. He is the best dumper diver I know!
