2. Act of leaving a shit moustache and beard on a partner's face by taking your cock out of her ass and putting it in her mouth without wiping it off first. The result is that as the dick is thrust between the lips, shit is scraped off and comes to rest all araound her mouth in a moustache and beard configuration. (kinda like a Dirty Sanchez but with the beard included)
