cross pound

A fist pound in which both participants cross their arms, make fists on each hand, and pound the other person's fists.
Seen from above, it would look something like oxxo with the o's being the people's heads, and the x's their crossed arms. A cross pound is used when a regular pound is just not enough.

To gather yourself, your significant other, and three additional couples in a van and drive around town stopping at four random locations for sex. At the first stop, everybody gets out of the van and has sex somewhere at the destination with their own partner. At each of the three additional stops, everybody swaps partners with a different couple. By the end of the night, everybody will have had sex with four different people in four different places.
