Island Fever is the realization that you are stuck on which ever island you are living and not going anywhere.
Sure, you can take a plane to Asia, United States and Europe if you have the money to pay for it. Most beach bums do not have it so they are stuck on Oahu.
Sure you can take a plane to Maui, Lanai, etc... But getting the money (around $100 RT) is also a problem too. Besides, don't forget SSDI... Same Sh*t, Different Island.
Person affected by Island Fever: "Seriously? Dude, shut the fuck up before I punch you in the throat."
Girl 1: What, you got island fever?
Guy 1: Totally.
Girl 1: Isn't it weird that Thai girls are so pretty and Thai guys are so ugly?
Guy 1: Ya.
