He's sooooo tuna!

Ok, I admit it, I use things like thesaurus.com. The other day, I was trying to find a new and unusual alternative to "handsome". What do I run across but the word "tuna". Now really, does that make any sense? lol. I ran it through dictionary.com thinking maybe I was just missing something but all I came up with was definitions for the fish. Somehow I get the feeling if I were to go up to a guy in a bar and tell him he was really "tuna", I wouldn't have much chance for a date.
