A Reverse Whoosh occurs when someone pretends, as a joke, not to "get" someone else's joke, by satirizing someone correcting the original joke teller. When others, in turn, try to correct and mock the stupidity of the person pretending not to get the original joke - only now in earnest, thereby revealing their own stupidity and lack of humor - they themselves have fallen prey to the old Reverse Whoosh.

Derived from the 'Whoosh' reply to a joke which goes over non-intellectual heads. Originally signified by waving the flat hand just above the head.
The 'Woosh Parrot' was developed as a medium to convey the same message in a visual form for internet fora such as 'Pistonheads'

When the other party not only doesn't get the joke, they don't get the explanation either.

Guys that have bangs and they flip it a lot. They always make sure their hair is perfectly wind-swept. Like: Jakub Andrew from heyhihello :) and justin bieber.

A whoosh bag is somebody who acts very similarly to a douche bag but maybe just because they are high or drunk.

Referring to something which was briefly in existence or evident and which is quickly removed or which rapidly disappears.

An acknowledgment of someone's awesomeness, Supercamp style. Takes multiple forms, including Power Austin Powers, and many many others.
