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.

bronchial backfire

Refers to da often-moderately-painful experience dat follows an especially "heavy-duty" cough, burp, sneeze, etc. --- a small amount of stomach-acid will travel upwards into the throat and create an acrid burning sensation.

Shortly after consuming a large meal is one of the most notorious times for a bronchial backfire to occur; it's wise to have a large glass of water or milk handy to hastily swig from in case of mishaps like this.

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
