Tuna Boat

An excessively obese female. So large that calling her only a tuna is not substantial enough to describe how oversized she is. One big ass bitch.

Damn that bitch is tank, what a tuna boat.

2.) A song by Lonely Island

Person two: "I'm on a Boat!!!"

Person one: "Hey, did you hear that song by Lonely Island, the one about the boat?"
Person two: "Oh yeah, I'm on a boat? That song is amazing."
