My wife walked in on me while I was cranking out a Wrap-N-Jack.

jack'n-danny

A lady's fury-cup, originally from the cockney rhyming slang for 'fanny'. (it should be noted that to the English the fanny is a beaver not an arse.)

Jack'n and Jill'n 

Self masturbation while your masturbating arm is interlocked with a partner who is also self masturbating.

It's not gay when you're Jack'n and Jill'n.

Jack'n and Jill'n is like a {dutch rudder}, but you don't need to wait your turn.
