Rounding up the "E" farts is the "important" one....
A very loud clear fart by a very important person is an Executive Fart. It is either sharp or flat, somewhat off key, but otherwise a very business-like fart. No nonsense about it. But no one is supposed to notice. Particularly the farter. If you do not laugh at the Executive Fart this is either because you are scared of the person who farted or because the fart is so gross. Common with very important people.
Although not "executives", I experience this fart quite often at work. Mostly from older customers who either can't tell they're farting, or don't care that they do. It can be quite smelly!
On the other hand, I am guilty of doing it at work too, and blaming it on bad produce or rank meat. Gotta love it!
