butt rifle 

A fart that is one single loud explosion. A very loud and if not controlled properly, could hurt the shooter.

Damn Lenny, did you hear that butt rifle?

Butt Rifled 

Having anal sex so intensely that ones anus becomes rifled like a gun barrel, therefore making poo come out like a soft serve ice cream twist.

Last night was crazy fun! My husband finally gave me some booty love. I woke up this morning and realized I got butt rifled when I went to the restroom and flushed just to see a chocolate covered cone disappear down the toilet.
