Ruddar 

The unexplained ability of rutters to quickly locate and befriend other rutters in any given area.

(Example is that gay people have so called, ‘gaydar’ so rutters have ruddar)

My new neighbor just moved in from out of state, and he must have ruddar because every dirtbag in the neighborhood has been at his house.

Norwegian Rudder 

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.

Hey you want me to suck you off? Nah, John just Norwegian ruddered me.

ruddering 

When someone uses there hand to knock a standing man's flacid penis from side to side. The equivalent of motorboating.

Can also do 'tennis ruddering' when you use both hands and bounce the penis between them.

Also possible to do it up and down or with your foot.

Surprisingly satisfying for both particiants

Guy "can I motor boat you?'
Girl "only if I can do some ruddering of you after"
Guy " oh yes please"

Female version of the dutch rudder
Having someone complete the act of masturbation by pulling up and down on the forearm, while the female inserts fingers into her vagina
