C&F means cocky and funny.
As for "pimping your Facebook", base it off yourself. Don't add something or say something because its "cool", do it because it suits your character. I have pictures of my car, and pictures of me from parties, and pictures of me just messing around. But my profile picture is of me chilling in physics with my head against the wall. I'm laid back, so it fits. Also, post on peoples walls. Make yourself outgoing, make it fun.
Here is my profile pic...
