Is what you do when your parents arent home. If they are, that may be dangerous. It means masturbation in case you didn't know. Its also a funny way to say it.
(no parents in your house):
You: *fap fap fap*

(with parents in your house):
You: *fap fap fap*
Your mother: (opens door) Son i need that...
You: *fap* HOLY SHHI- (falls down the bed, grabs everything and does a tornado flip)
Your mother: (closes the door)
You: FFFFUUUUUU...

Originally the onomatopoetic rendition of male masturbation in Japanese manga (erotic comics), using the Roman letters. "Fapfapfap" has come to represent male masturbation in general, and by extension the slapping sounds of any anal intercourse, and male/female penile-vaginal intercourse as well.
-- What did you think of that new actress?

-- HOT! Fapfapfap.

-- Easy for you to say.

-- Give me some privacy and my dick will make the noise.
