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.
Sam and me had fat people sex last night. I think I broke my ribs.
