The sex juices excreted from a vagina during masturbation. Deriving from the verb 'to frap' and the noun...'juice'.
OH SHIT! I just got a whole bunch of frap juice on Auntie Rodney's Egyptian cotton drapes, pass me some Vanish Oxyaction or some shit, this stuff is like red wine! maybe I should pour white wine on it? they say that works right? Oh fuck, here she is now. Forget it, Ill just say it was the dog who frap juiced all over her prized cotton drapes.
