|1.||Mexican Sack Wave|
Similar to a sack tap but it occurs during anal sex.
It involves several men linked by their penis and ass in a circle. When the man at the back thrusts vigourously, his sack strikes the sack of the man in front, who in turn "sack taps" the next. This then continues around the circle in a wave.
Dawg, that mexican sack wave was wacked last night... we got three rotations!
