After unleashing one’s boner marrow into a whore’s mouth and she has the audacity to spit out your load, you proceed to bitch slap her across the face while wearing a ring, (preferably backhanded but forehanded is acceptable too). As long as it tears her facial tissue, leaving a scar that will remind that whore to never spit out your cum again. You then shove her face in the ground, (creating another gash in her face), and make her slurp it up off the floor and swallow it like a true whore.
That whore Marci spit out my cummies, so I felt obligated to give her my specialty, The Scarface.
I busted a huge load in Marci’s mouth, but I had to Scarface her when she didn’t swallow every last drop.
Mimicking that scene in the movie Scarface, when Al Pacino drags his face through a pile of cocaine. An expression of extreme desire and excess. Can be applied to anything that is so awesome that you'd literally like to put your face in it.
I'm so hungry I could scarface through a whole cake.
Or: She's so hot that I'd like to scarface her crotch.
