the few tiny hairs that grow on the sides of a persons upper lip. often seen on mexicans and young boys who can't grow in a full mustache yet. reference to the "mustaches" on catfish.

sorry, you can't grow a real mustache yet, but those little whiskers on the sides of your lips are shaping up to be a pretty good catfish mustache

Catfish Moustache 

#1. The invisible stink residue left over on the face after eating a girl out who was either absent the day they taught how to clean the vag area in 8th grade health class or just returned from a run before intercourse.

#2. Hairs left around the mouth after eating out a hairy ass (either guy or girl).

I need a shower bad to wash off the stank on my junk and the Catfish Moustache off my face. It smells like a dead pirates swass.
