Frap is to masturbate. It is the word Americans should be using after they stopped using jerking off so much and started using the quite erroneous fap. They are unlikely to do this however as they seem to have a lot of trouble spelling many English words.
Frapping was originally the way in which a rope is tied to some logs or oil drums, for example, to make a raft in watermanship.
Frapping was first used to mean masturbation on a British army assault pioneer course circa 1991. I know I was there.
"Stop frapping your privates private and get frapping that rope to that oil drum"

"Stop saying 'fap' you American idiots what you really mean is frap"
