freezer fart
when you let one rip in a cold place, such as a restaurant's walk-in cooler. Low temperatures have a stench-enhancing property when it comes to farts, so when this act is performed, not only does the fart stay enclosed in the cooler until the door is left open long enough for it to escape, but also smells about ten times worse. In general, freezer farting is a fun and hilarious thing to do.
I ripped one helluva freezer fart in the cooler at work today. Joey went back there to get something and the smell was so bad his eyes started watering. Good times.
