A Dirty Mustache

When a lady shaves her nether regions besides her lips

Guy 1: how’d your date with Stephanie go last night?
Guy 2: ehh, I was about to go down on her, but she had a dirty mustache and it turned me off

BitchTaco

1. that one Mexican mom in her 20's with already 9 kids (and counting)

2. a word to call your friends when they're being assholes and you're in an "interesting" or "creative" mood

1: Julio's mom is from an Asian decent, so is NOT a bitchtaco
2: guy 1- why do you have to be an ass-swab?

guy 2- depends, why do you have to be a bitchtaco?
