CTFO is an acronym for Chill The Fuck Out. It was popularized as an everyday term by a Washington DC resident named Bryce, who attends the Maret School. Others may try to take credit, but Bryce actually did invent and popularize this phrase, after the surge in popularity of WTF. You are supposed to pronounce every letter in the word (ex: see tee ef oh)
Where the hell are we supposed to be?

Chill the Fuck Out . Unlike previous postings where "Bryce" from DC has claimed to have invented this word- that is just not true.
