When a female or male give a man a handjob while in the bath tub or hot tub when it is full of water. In this situation, the hand would be the tugboat whilst the penis represents the boat being tugged.
Dude, when we got home, we decided to relax and get in the hot tub and she totally gave me a tugboat!

1. A male who must keep one member of a group afloat and with the program much like a tug boat has to keep a barge afloat and going in the correct direction.
2. A male who often must pull along less motivated participants within a circle of friends. They are often loud, humorous, and unrelenting in their passion for having fun and finding shananigans. A Tug boat will not stop untill all necessary participants are aboard with the evenings plans, regardless of how much his friends' girlfriends dig their heels in the mud and say NO!!!
1. Spunk needed to be dragged out sometimes, much like a barge, by the group tug boat.

2. Greg was such a tug boat regardless of how tired Matt, Lauren or Spunk were he always got them to go out and have fun!
