Wet spelunker

Another name for a dick/cock. In particular after having had sex in a wet pussy or ass.

Derived from the concept of exploring a dark cave which is usually very wet as can be seen with a pussy and ass after lube is applied.

The wet spelunker bulging in Davids pants was making it hard for Taylor to concentrate.

Internet Spelunker

An internet spelunker is someone who wanders the web looking to find unusual, old, and hard to reach information. They may do this in many ways including but not limited to browsing TOR, deep webbing, torrenting, looking for obscure search terms, browing 4chan, and following links on defunct web sites. Internet spelunkers often have large collections of unusual images and strange web addresses they have found and can find almost anything you're looking for nomatter how obscure even if it may take them a little while to find it.

Damnit, 4chan has failed to find the source of that pic. Anyone know an internet spelunker?
