The (sometimes fatal) rush of hot, noxious gas that escapes from between your legs after farting whilst sitting on the porcelain throne.
This is particularly hazardous when hung over after a night on the Guinness, as the unsuspecting victim hangs their head in shame between their knees, whilst the world falls out of their arse, and a gust of rusty wind has nowhere else to go but to escape up and out from between their legs right into their face.
“Oh Sweet Baby Jesus and the orphans!”
“What’s wrong, Darling? Are you ok?”
“For Fuck’s sake! I’m sitting on the pot to have a Richard the Third and let out a huge fart. The backdraft shot right up and hit me in the face. I wish I hadn’t eaten that vindaloo last night.”
“Oh dear. You poor thing. Do you need me to come in and help you?”
“No thanks Mummy, I’ll be fine.”
When you're chugging a beer but the pressure of the beer flow shoots up from the can into your nose.
I threw it back too hard and the backdraft of the can shot up my nose.
The semen ejaculated from inside of a "water snaked" or water snaking it" set of conjoined penises. The backdraft effect occurs when one member of the set of masturbating gay men organs and ejaculates inside of the other's penis while the two penises are docked and being gripped tightly by the maturbating member of the water snaking duo. Note, because pain is normal for the backdraft recipient, finishing first is often a race between the stroker and strokee.
The two gay men lovers raced to backdraft inside of one another's penis.
If blowback means long-term consequences of secret or unknown foreign policies that catch the population off guard and leave them open to false interpretations about the nature of the conflict, backdraft means the short- term consequences of overt policies blowing up right in our face. – author Scott Horton in Enough Already: Time to End the War on Terrorism
Despite government lies that Omar Mateen was driven by repressed homosexuality, in fact, his 2016 Orlando terrorist attack was backdraft from Obama's bombing campaign against the Caliphate he had helped to create in Iraq and Syria just a couple of years before in an attempt to oust Bashar al-Assad from power in Damascus.

The homeless man had a horrible backdraft.
The act of farting directly into someone else's butthole.
As my sister laid on the couch, I gave her the gift of the unexpected backdraft.
note: This takes some planning, a pair of nylon gym shorts, and willing ..or unaware partner to work. When a guy has been doing an athletic activity and has swamp-sack (foul smelling scrotum) he will close one leg opening tight and then he gets his significant other to blow air up his shorts only to have the air circulate and exit back out the same leg hole into her/his face.
I plopped down on the couch after finishing my run. I told "Jane" my nuts were hot so she decided to blow up my short to "cool them off" but I closed off the other leg and she got the "Sweaty-Sack BackDraft"
