look up any word, like ratchet:
A 'venura' is the prevailing colloquial term in many parts of Eastern Europe and Kenya applied to passengers who engage in vigorous, sustained, and often festive displays of masturbation on commercial aircraft and public trams. 'Venuras' statistically tend to be itinerant pide salesmen. They have anecdotally been known to have a penchant for sodokus and appearing on airport security databases.
a). Captain, what should we do, looks like we've got a real venura in 14F.

b). He's a through-and-through venura all right, just about derailed the bloody tram.
