CF

An abbreviation for "childhood friend." Meant for online, but never in real life, because that would be weird.

cf

Short for casual fapping.

It's like foreplay for masturbation. Also done out of boredom sometimes.

cf means casually stroking one's dick without any real intention of reaching climax (yet).

"Yo, what are you doing?"
"I'm bore, so just some cf."
