J.F.C.
J.F.C. is the abbreviation of the popular phrase "Jesus F*cking Christ". Its most obvious definition is to be surprised by a recent event that was just way too f*cking unbelievable. Sometimes in events of even more epic lulz, it could be used in a way that hints that it could have possibly been foreseen, which it is then compared to the phrase "that was ironic as f*ck".
