What is Dirty Lathrop?
1.
This is when a guy and a girl or a guy and a guy, (no girl and girl because they dont have propper "tools")are haveing anal sex and right before the guy cums into the guy/girls ass he pulls his "tool" out and the partner rolls on their back and the first guy draws a smiley face with his cum on his partners chest.
