the sexual act of a woman riding a man to orgasm. Then while still straddling him post coitus, takes their collective juices in hand and smears the fluids across her forehead. To complete the activity, she headbutts him in the face with everything she has, hopefully knocking him out cold.
Raechel hit him with the smunch. he looks like he caught a baseball bat to the face, but he said it was totally worth it.
