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..."
