Spelunking

When a girl is naked and asleep under the covers and you get a flashlight (or a cell phone will do) and check out the goods. Usually done when you first sleep with someone, but can be done with girlfriends, friends, whatever.
A girl can perform this on a sleeping dude as well.

Laying there next to his hot one night stand, the perv grabs his cell phone and goes spelunking to get a closer look at her love clam.

spelunking

the sound your dead lifeless body makes when it lands in the bottom of a large chasm in a pitch-black cave you thought was cool to check out

The medical examiner explained the body was found in the chasm of a cave no doubt the deceased was spelunking...poor bastard

spelunking

Having sexual intercourse with a girl who has a very wide and stretched out vagina. The vagina is very cave-like due to its constant past use. If you are considered to be spelunking, then the girl is a whore, and you will most likely contract a sexually transmitted disease.

I only had to pay five dollars to go spelunking in your mom
