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

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

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.

Old Faithful

When you’re asspumping a dirty tramp face down on your mattress and feel like it’s that time time of day. Your dick hurts and it’s time to take a piss. With your Johnson stuck deep in her rectal cavity, you strike a firm blow to the back of her head in order to make her ass tighten up so there’s no way out of it for this bitch, then proceed to leak in said area until you feel the tank is properly full. As she screams in disbelief, swiftly remove your genitalia from the region. This should produce a large eruption of your unloaded piss which exits the asshole with astounding velocity, mimicking the famous geyser located in Yellowstone, Wyoming.

Her: What the fuck, did you just piss in my ass?!

You: (Whips out phone) Holy shit it’s old faithful!!

Old Faithful

Getting a blow job while sitting on a bidet getting your asshole cleaned.

I was in the bathroom after I took a shit. My old lady came in and gave me an Old Faithful while I was in the bidet.
