Signature white guy dance move. Typically used when dancing with a member of the opposite sex. As the partner moves close to a guy on the dancefloor he will tend to squat very low, with his groin somewhere in the region of her mid-thigh to kneecaps, and grind in her direction. It is appears to be highly uncomfortable and inefficient.
I tried to twerk this rump on his junk but he was "white boy squatting" and I wasn't trying to get that low in these heels. Way too much stress on the thighs.
