If you ask people who actually go caving, spelunking is the derogatory term for stupid or unprepared cave trips. Origin: "spelunk" is the sound a clumsy caver makes when he slips and falls in a cave and lands in water.
If you don't take a helmet, more than one source of light, and a few friends into the cave with you, then you're not caving. You're spelunking.

1. (v) To explore virgin caverns, and or orafices. Best practiced with a helmet and possibly a light. (Unless it's scary looking, then forgo the light, but be sure to use the helmet!)
Timmy, my next-door neighbor and play-time doctor is multi talented--an accoplished physician and an experienced spelunker.

The act of engaging in sexual relations with a woman who has a large, dark and cavernous vagina. This act of extreme desperation and bravery is usually reserved for men who have gone more than three weeks without getting laid, and who are willing to submerge themselves (without safety equipment and/or flashlights) without preparation into a vagina in which many enter and few return.
Examples:
"Koumi was one of the ballsiest spelunkers I have ever seen: he used to fuck XXXXXX without a condom or a GPS system"
"Guys, we lost one of our own today. I just got word that Andrew Tha Owner" died on a spelunking trip yesterday. He was in Wunsch's Cave when he sprained his ankle, and was unable to escape. He eventually ran out of air, and died."
