fik or f.ik or f.i.k (for those who are extra OCD) is an acronym for sms which stands for "Fuck I know". Usually used when a surprise element precedes the usage of fik.
Mike: "Dude, did you hear that Tammy got pregnant last night."

Twohy: "FIK, it's gonna be her third kid and that chick is only 18."
