Constant fuck. Not your bf (boyfriend) or gf (girlfriend)... just the person you constantly fuck.
Guy 1: Hey man is that your gf?
Guy 2: Nah thats my cf.
The word "Cf" (pronounced "seff") is an abbreviation of the word "Seff", which is an abbreviation of "selvfølgelig", which means of course. Cf is a very cool word used only on chatrooms and facebook, never when you talk (when you talk, "seff" is used instead, although these two words are pronounced the same way), and only by the wickedest of the wicked.
Cf I'm going to be on MSN today!
it can mean either
1. close friends (on instagram stories)

2. can’t front, meaning you can’t lie
1. “who wants to be in my cfs, swipe up”
