When you’re in the bathtub, Butthole to Butthole and you fart into each other’s butts creating a wind tunnel

Man, we sat in the bath and wind tunnelled eachother.

Polish wind tunnel

When two sexual partners are both on all fours, facing opposite directions so their butthole are eye to eye and they keep passing the same fart back and forth into each other's anus.

You can tell those two do the Polish Wind Tunnel to each other; they're from Missouri, after all.

Piss in the wind tunnel

Peeing in someone’s butt while she farts on your penis.

Going to have a piss in the wind tunnel again.

Human Wind Tunnel

The act of farting while simultaneously taking a rip from a bong.

The room fell silent as Becka filled the chamber of her bong with thick, white smoke. As she cleared it in one breath, she let out a thunderous fart that sent her friends into fits of laughter as they bore witness to the Human Wind Tunnel.

Czechoslovakian Wind Tunnel

The act of being tied down, unable to move, and then having a partner fart as hard as possible over the top of your head.

Chris: I'm tired of regular fart porn!

Stacey: You should try a Czechoslovakian Wind Tunnel!

Alabama wind tunnel

The act of scissoring buttholes together, one partner farts, the other partner sucks it in.

I invited my cousin Jenny over and we scissored for the first time. She came too fast so I clinched my butthole against hers and farted. To my surprise, she rectally inhaled.

We scissored buttholes together, I farted into hers and she sucked it right in. It gave me an Alabama wind tunnel.

Wind Tunneling

When two people go butt cheek to butt cheek with their assholes touching and they both fart simultaneously. This can be a planned or accidental event.

Last night was chill but sleeping in Sam's got a little drafty ...we ended up wind tunneling for most of the night. I blame my gluten intolerance.
