F-Shack

Fuck Shack, any enclosed area or location, usually cramped in size, that is used for couple or group sex. (i.e. a car, port-o-potty)

We found your car with a note inside:

"Thanks for the F-Shack. - Dirty Mike and the Boyz"

There must have been some homeless guys foolin around in it. We call that a soup kitchen.

f sharp minor 

the best musical key ever and nobody can tell me otherwise
-allows you to go into optimal bass frequency range
-decent number of sharp notes without being excessive
-sounds extremely pleasant in any chord progression. not joking. you can stick an f sharp minor chord anywhere and it will fit like a puzzle piece

guy 1: this beat that some guy posted is in f sharp minor. it slaps so hard
guy 2: nah you should check this other beat. its in c minor
*guy 1 immediately pulls out a knife and stabs guy 2 to death*

F Shake 

What white/Asian people do when they feel uncomfortable.
It starts with a fake laugh, then they shrug their shoulders, shake their head and make a weird face. Sometimes their eyes franticly move around.

Guy 1:"I just told mark he looks like a dyke"
Guy 2:"hahaha wut he say bak to u"
Guy 1:"Nothin, he jus kept doin the F Shake"
