An acronym to use when attempting to express the utmost disgust for almost anything, used most frequently when referring to something very poorly executed by you or a peer.
As I was writing my bildungsroman essay, my friend left a comment stating JFCTIS, and I immediatelyretorted with STFU, because I was too blind to realize my essay really was fucking shit.
it's the kind of face a person makes when someone says something utterly stupid, or when you drop something after you were trying so hard not to. It's like a "WHAT THE HELL" face.
You can also say it whenever something dumb happens. It's kind of like a "okay no" sort of face, you know? Everyone makes it a lot, they just never know it's a jface ;)
