YGBFFM 

You Gotta Be Fist Fucking Me

Yet a more vulgar, but none the less appropriate, expression of the phrase “Are you kidding me?”

Used when the recipient may mistake the rhetorical “Are you shitting me?” question as requiring an answer.

Generally reserved for situations in which the person uttering the phrase is completely discombobulated, or when flabbergasted due to the repeated demonstration of stupidity or ineptness by others.

Easily shortened to YGBFFM for texting purposes, or when uttering the phrase would have a negative impact to your HR file.

Coworker 1: “The IT department deleted all the files again.”
Coworker 2: “YGBFFM!”
