The act of opening and expanding the anal cavity of ones partner and then proceeding, with cave diving gear (ie: Carabiner, ropes, headlamps, etc), and entering the damp ridged caves of your consenting adult. Occasionally returning to the surface for air.

Originally termed in the movie "South Park: Bigger, Longer, and Uncut." Commonly mis-spelled as ass beehonker, this term refers to anal intercourse between two men. Splunking itself is decending into a deep cave, which is fitting.

Yo, Mike, when you get done ass-spelunking with Larry would you mind helping me get some work done or would you rather give him a hot carl.
