Splitting a handjob from a hooker with your homie to save money. The hooker will jerk both of you off simultaneously (that's why the have two hands) thus allowing you to split the hourly rate. This is typically only practiced within the Caribbean islands.
Friend 1: "Damn bro, I spent so much money on lap dances I don't have enough to get a handy. You wanna go to that whore house and split something?" friend 2: "sure let's go there and get a wankin' Caribbean Dutch rudder style!!"
A form of mutual masturbation similar to the Dutch Rudder. Each partner folds his leg over the top of the other's leg and begins to shake it, sending vibrations up the partner's thigh, and eventually to the tip of their penis.
