acronym for "cum to fast" It is an expression which defines the unfortunate occurence when a female overarouses a male, and as a resulst forces an involuntary ejaculation of the males penis.

Remember Jason Biggs from American pie?
Jim, despondent that he hasnt had sex his entire highschool life, was over exuberant and exicted when Cladia voluntary stipped in front of him.

Jim then CTF'ed, which depleted him of his reserves and sacrificed what could have been a score with the hot foreign chick.
