Fried Chicken Kentucky. A play on words on KFC. Means exactly the same , but is reordered in such a way, that it sounds like the word "fuck" for the funnies.
A: hey dude, what are you doing?
B: Eating FCK! It do be tasty.
The act of eating FCK. sounds a lot like "fucking", but it's a totally different thing. Sound hella funny and confusing.
A: What did you purchase, man?
B: I got some fast food for dinner.
A: nice! :)
B: Yeah, I will be FCKing tonight. I wished it was a perosn, though... :/
