mack face
the face you make when you see someone so hot you feel like you're going to cum just by looking at them
My cousin saw his ex at the mall and made the worst mack face ever. I swear I could hear him thinking about sex.
She walked in and gave me the mack face. I was like, 'What the hell is that?'
He gave me the mack face during class. I had to leave the room because I was too distracted.
