An ugly or fat girl.
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.
