When all your friends catch you Scoping other guys asses all the time. Very shameful, but it does happen.
Guy#1: "Hey, stop checking out guys`s asses"
Guy#2: "Im not, I was..."
Guy#1: "Yeah whatever, butt rifle"
Guy#2: "Im not, I was..."
Guy#1: "Yeah whatever, butt rifle"

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

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.
