The Ninja: A classic example of the phrase silent but deadly. Is almost entirely inaudible but has an ungodly stink.
TNT: A loud but not too stinky fart.
Nuclear Bomb: A jack-of-all-trades fart, stinks really bad and is also VERY loud. The worst ones to accidentally let loose.
The "Taking A Dump" Fart: Self-explanatory.
The "Taking A Dump" Nuclear Bomb: A rare kind of toilet fart. Acts likes a Nuclear Bomb. The leading cause of public bathroom embarrassment.

The Volcano: A powerful kind of shart. Can also be mistaken for a TNT, but the shit may be so violently released that it can escape your underpants, causing extra embarrassment.
Krakatoa: A loud and very powerful shart. If you get this, go see a doctor because you probably have diarrhea.
The Trampoline: Very loud, but with zero stench. The force , however, is strong enough to launch yourself forward a bit. Usually caused by comfort foods that produce a lot of dense gases.
Shit-Flavoured-Air: The most ungodly stench known to man. A chemical weapon more toxic than Sarin. The clearer of rooms everywhere. The origin of humanity's concept of demons.
