This is a dutch tugboat when your buddy isn't up to fucking the hooker you just paid for. So you take him sailing out to sea via the tugboat. Don't forget to bring him into the harbor (her snatch).

The northwest form of a Cleveland Steamer. It is critical that you eat a large quantity of Mexican food before preforming the Seattle Tugboat so that you have diharria. You then crap on the girl's chest and slide down with a "toot toot" noise, more like a tugboat.
Dude 1: Man I gave this chick a wicked Seattle Tugboat last night!
Dude 2: I didn't know you had a girlfriend!
Dude 1: No, man it was your girlfriend!
when you tie your wife to the side of a docked tug boat and munch on her va-jay-jay for hours on end while making the noises "nom-nom-nom" and "toot toot"
