Stands for "Camp Friends Are Best." it is used to refer to camp friends in all situations: while talking to your camp friends, while talking to other people about your camp friends, or really just any situation involving camp friends.
I wish I could hang out with you tomorrow, but I'm going shopping with CFAB.

(a facebook status) I'm going to camp tomorrow! CFAB T-1 day!

Said when someone is winding you up, especially when using acronyms and grammatically dubious ways of doing so like "My bad" and "LMAO"... Enough! CFAB!
