Fwap is a slang term for male masturbation. The origin of the word is believed to be onomatopoeic, though may be an acronym (or equally likely, a backronym) for Furiously Wanking At Porn. It is in common usage amongst the b3ta web community.

To "fwap" is to swat someone over the net. It adds a sense of comedy, "drama" or even some playfulness to it. It makes a swat seem less boring.
