Facial Spelunking 

The hobby or practice of exploring the caverns of the face.

Often practiced in tandem with booger bombing.

Cube slave 1: "Dude, I'm soooo damn bored..."
Cube slave 2: "You should take up facial spelunking."
Cube slave 1: "Man, I'm so past that, I've been booger bombing you for hours..."

Greek Spelunker 

The act of inserting an illumiated flashlight into a female's rectum, then spreading her labium with both hands, attempting to "see the light"

I lost my class ring in Kristen's gaping cavern, and had to perform a Greek Spelunker in a valiant attempt to recover the lost treasure.

Friend 2: ima go mancave spelunking for a while, see where it takes me...
