1) A tattoo on the lower back of a female. Called a cum catcher because the lower back is where a male ejaculates on a female after
pulling out after
doggy style sex. Refers to the belief that girls with lower back tattoos are promiscuous.
2) A mustache (can also refer to a goatee). Cum catcher implies that the man gives oral sex to other men, thereby
catching cum around his mouth.
