When a man lays a woman on the bed on all 4's and uses a dental device that is often used to stretch open someone's mouth for dental operations, to stretch out the female or males anal cavity to a width wide enough to fit a bong. From there the man then packs a bowl of that afghan grass and puts it into the bong and lights it, the man will then proceed to take hits from the bong. Sometimes this can also be called wind swapping or ass gassing. This sometimes can also flavour the smoke with the scent or taste of the receivers anal cavity.
"Hey Dad!"

The act of having someone fart into one's mouth. Similar to a Miami Trumpet, except that the recipient not only expects it but desires it.
I need to load up on chili tonight - Burt is coming over later and he said he's up for some hot Darien Wind Tunnel action.

Farting while engaged in 69, giving a Dutch Blindfold, or at any point where the person giving you a blowjob's head is between your thighs.

When a fellow family member sits on your arse while you lay face down and let's one rip straight up your stinkhole then holding on as the victim tries to buck you off in absolute disgust.

The act of farting while performing a reverse titfuck (where the man's butt is over the woman's face). Named for the sweet scent of the Midwest.

When a man farts into a girl's butt causing the "wind" to travel through her insides and out her mouth in the form of a disgustingly stinky burp. Her mouth then smells like a fat, hairy guy's ass for 2-6 hours depending upon her penchant for hygiene.

This is often done in Windsor (Canadian city right outside of Detroit, MI) as everything in Canada is ass backwards and dirty...
I don't know whether this girl I met ate a pig's ass for breakfast or she ran to the bathroom and got a WINDSOR WIND TUNNEL from some dude...Her breath is nasty!

Refers to someone stumbling and having a hard time standing up straight without swaying when drunk (because they look like they are walking through a strong wind tunnel).
Oh no, Mike's wind tunneling down the hall. Guess he shouldn't have had those extra shots.
