yes, very much so
A person who has sex with a fat and/or ugly girl is called a Land Monster Slayer.
If you know anyone who has sex with fat or ugly girls, it would be correct to begin referring to them as a Land Monster Slayer, because they, in effect, defeated the Land Monster at her horrible game.
Guy 1: "Those 2 chicks over are total land monsters."
Guy 2: "Definitely, man. I haven't gotten any in a while. Want to go slay the land monsters with me tonight?"
Look at all those land monsters over there, I'll pay you 20 bucks to sleep with one of them...
