fapfapfap

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.
