double dutch rudder 

Interlock your manhood with both hands and have two lady friends on either sides working your arms for you. It very much helps if they stay in synch.

After the Xmas party at the Moose, Pam and Sharon gave me a double dutch rudder, causing me to paint the ceiling with a most powerfull release.
