"That drunk boat just tried to force a tequila bottle down Jim's throat!"
A person that you appreciate immensely. It is also the title you receive after you've done something awesome. Depending on the awesomeness of the action you might even be a delicious canoe or a delicious cruise ship or a hooker boat.
The opposite of a delicious boat is a malicious boat.
