Fulldin Butt (Pronounced Full-Din- Butt) Is a butt, normally a female's butt, where the lower-half sticks out, then folds back up unto the waist. Much in the way a beer belly hangs over the front of a pair of pants. Examples include: Jessica Alba, Jamie Pressly, and Roselyn Sanchez. Not to be confused with a Bubble-Butt, which is just round and sticks out like a bubble. Or a Flat-Butt, which just extends out slightly, but does not fold underneath.
I saw this really skinny chick with a Fulldin Butt. I couldn't believe someone so small could have such a thick ass!

Get the Butt-Hat mug.When angrily smashing your bird in the anus withdraw your penis slowly to cause suction and poo will follow. Then squash the faeces between her bum cheaks and slowly pry appart to reveal brown angels wings imprinted on her ass cheaks. Then finish yourself off in her vagina with your shitty cock.
