The act of standing over your man/womans' face, after working up a dripping sweaty ass crack, and then proceeding to squat down (lining up nose and asshole) grinding forward and backwards. When satisfied, stand up and blow a load on that sopping wet face.
My boo loves the New York Grinder. The taste and everything. I'm so glad my mom gave me a walk through.
