Eat penguin shit, you ass-spelunkers.
by alerish March 03, 2003
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.

this word comes from ass meaning butt and spelunker meaning someone who explores caves so ass spelunker means someone who explores the butt hole and its surrounding area
