Fart Opera 

When you are laying in bed in silence and you release a long multi pitch fart that sounds like a chorus.

Omg, Dave woke me up in bed last night with longest, noisiest fart. I swear the windows were vibrating! It was a fart opera.

Fart-Opener 

A fart of such noise and strength it can just open a bottle of beer to open a cold one with the boys

"Dude I swear to God I had Fart-Opener last night, it smelled! "

Open Air Fart 

A release of a fart outdoors that is so dense and vile that not even a breeze, strong wind, or any other weather related condition can safely disperse the heinous ass gas before it makes its way to all surrounding victims’ noses. Even moments later, this thick and gaseous hell-beast of a rectal belch will stay lingering in the same outdoor vicinity in which it was spawned.

The family cookout was going well this past weekend, until Bobbo laid an open air fart that cleared the entire picnic area and almost killed his already unhealthy, jaundice looking friend, Smear.

Minutes later when EMTs arrived to collect Smear, the lingering aroma of Bobbo’s open air fart forced them to wear decontamination suits and oxygen masks in order to enter the hot zone.

open throttle fart 

Letting one rip with abandon and without care for the safety and well-being of those near you.

Jimmy let an open throttle fart out while he was next to me at the urinal, it's poor bathroom etiquette.

Open-Anus Fart 

When your fart opens your anus releasing a wad of air while producing no noise.This fart can either be stinky or have no smell at all. If your stomach hurts than your fart will be hot and smelly.

I just farted and it was open-anus. My stomach hurts..did you smell it?

Open-Anus Fart 

While at the office, casually walk over to a co-worker as if you have important news. When their guard is down, drop trousers, and in one motion, spread your ass-cheeks as far as possible with your hands and bend over releasing pure gasseous matter directly into the unsuspecting victims face. AKA: OBH (open butthole fart)

I couldn't believe it when Josh open-anus farted right in the middle of the office. His ass was right in my face.
