Old Faithful

The act off nutting (ejaculating) inside someone's mouth while they are on their back then stomping on their stomach. Those wearing a Used Poncho can avoid the geyser's angry eruption.

My girlfriend took one in the mouth from me last night so I stomped on her stomach, thus completing the Old Faithful. Wish I would've had a used poncho on...

Old Faithful

A sexual act. It is when you pour an entire bottle of lube into a girls ass. Then, upon the first thrust, the lube sprays out like a geyser.

"Whats all that lube for"

"Yellowstone, here we come, Old faithful, baby."

Old Faithful

When you place a heaping amount of cocaine on a girl's butthole and do a bump. Must be done quickly before geyser explodes sending flakes everywhere.

Why don't you drop those drawers and let me get an Old Faithful off your sweet meat?

Old Faithful

The action that occurs when a male receives a blow job, then just before reaching orgasm the subject performing the blow job punches the recipient in the stomach, causing violent eruption of bodily fluids and substances from all orifices simultaneously.

The night was off to a good start up until Sally initiated Old Faithful, causing the night to come to a screeching halt.
