When a woman finger-fucks her boyfriend in the ass and then rubs her soiled finger on his upper lip, creating a smelly shit mustache. This offer null and void if he already has a real mustache. Similar to a Dirty Sanchez, but one for the girls.
I got so sick of my guy asking me to finger-fuck his ass that I gave him a Dirty Miguel to teach him a lesson.
