Blumpkin Backfire 

When you have received so many Blumpkins that you can only orgasm when you smell shit. When people fart you wind up following them around, nose to their ass, and jacking off at the same time. Instead of flushing the toilet after you pinch off a biscuit you leave it there for months, because the more rancid the odor the farther you shoot your load.

Blumpkin Backfire (adj.) "Fuck man I was with this hot slut on a date, and the fat guy next to me farted... next thing I knew I was butt naked jerkin' my turkey and spitting up mayo all over my ho's tank top!"

backfire at the disco 

1. to fuck up whilst hitting on a girl.
2. the name of a song by the popular liverpool band the wombats. based on an incident of the same type featured in item one.

It's 8 o' clock and I'm feeling fine
I'm out on a date tonight
In a candle lit restaurant down by the riverside
Everything’s going alright I guess
She took down my number and home address
Everything was going perfectly until...

It backfired at the disco, she slapped me at the disco, I did something I'll never forget

It was a chat-up line built not to impress
More a sleazy remark on her whorish dress
My wires crossed like they've never done before
Well it's 3 o' clock and I'm feeling shite
I'm going home alone tonight
I made a move when it was well out of context

It backfired at the disco, she slapped me at the disco
I did something I'll never forget
It backfired at the disco, we were dancing at the disco
I made a move when it was well out of context

It backfired at the disco, we were dancing at the disco
It backfired at the disco, we were dancing at the disco
Yeah, it backfired at the disco, when she slapped me at the disco
It backfire at the disco, we were dancing at the disco

the wombats song describing how the lead singer 'backfired at the disco'.

backfire 

To hit back.

When you are clogging the toilet with your massive, brown logs of divine terror, the brown water that splashes up on your butt and balls is known as a "backfire".

Dayum, that shit really backfired.
