Thunderbed
Thunderbed is the competition between two males in which each male must attempt to successfully penetrate and rape the other man on a bed. (The play area.) The competition ends when one opponent successfully mounts the other or a single opponent yields. It's not gay, it's about dominance.
"Man, there were so many guys around, I almost resorted to Thunderbed for entertainment."
