When 2 very fat people love each other and want to express it through 1000lb sex.
Or when 1 fat person tries to shove his miniscule member through the other normal person's orifice, resulting in - fat people sex.
Usually ends with one person passing out or both stopping for a cake break and then passing out of exhaustion after getting to the kitchen.
Very loud and disgusting. Like when a dog takes a shit but you cant look away.
The kind of fat that is on a girl around her mid waist which makes her not skinny but not fat. Its the kinda fat you want to fuck. Used like in the phrase "more cushion for the pushin' " without the girl being incredibly fat or unsexy
