look up any word, like rimming:
A dooder shank is reffered to as a partial erection recieved when in an automobile, usually a bus or a taxi. One may recieve a Doodershank plus which is a full erection.
It is widely known for a Dooder shank to be cuased of vibrations rather than a regular NRB.
I got a mad Doodershank on the bus ride over here.
