Term used to describe the type of activity required to have produced the mystery damage that sometimes appears on your body after a night of heavy drinking.
"I have no idea how much i drank last night, but i must have been doing some serious naked bobcat wrestling to fuck myself up this bad."
The two combatants strip naked. A belt (or equivalent) is placed behinds the two competitors necks when facing each other on all fours. On 3, the wrestlers (when bound) attempt to back away from each other (as iguana do) and the first to cross the starting line (the original midpoint of the two) loses.
