A term used to describe having sex with someone who is large or has less than desirable physical qualities. It was coined one night when a invitation was sent out to join a party with a "extra large" sorority. When considering to accept said invitation, a man we will simply call JJ calmly said "lets do it, lets tank the whale".
So i went to that girls house the other night and we started to get it on until her room mate walked in and totally saw me tanking the whale.

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.

Usually used by people with poor typing skills. Most of the time, it is a misspelling of "thank you", but can also be used after or with a joke about tanks.
