Backfire on Her Tongue

When a girl is licking your ass and you slide out a small amount of poo.

When Roxy was licking my ass the other night I couldn't resist to squeeze a little one out.

I ended up doing a backfire on her tongue.

Muffler backfire

When a girl is giving you a blowjob, and while choking on your dick, she accidentally farts.

So my girl was choking on my cock, and had a little muffler backfire.

I think my girl had to shit, because while she was gagging on my cock, she kept hitting with a muffler backfire.

Backfire

/bakˈfʌɪə/
noun:
The sensation of pain one might find emanating from their behind whilst defecating, caused by one having ingested a particularly spicy meal the day prior to the defecation.

It feels like my back is on fire and it's my fault - I knew eating 2 pounds of delicious jalapeño dressing yesterday would end up backfiring and that I would end up experiencing horrid backfire.

Hormonal Backfire

The guilt you feel after ejaculation if you let your hormones take over your rationalization skills and you become really dirty-minded towards someone else in which there's something to regret afterwards.

Jamal: Dude I sent nudes to Jessica and I felt scared later
Mike: Sounds to me like hormonal backfire
