1 definition by Simon Ham

Alternate term for sport utility vehicle or SUV. Any large, ugly, innefficient, fuel guzzling vehicle. An urban "tank" driven by an urban "wank"!
I often choke on the fumes from wank tanks left running on the street while I'm walking around town.
Those Hummers are the ultimate wank tank.
