A type of food/drink where a small hole is cut into the top of a watermelon, and a bottle of alcohol, generally vodka, is poured into it. The watermelon is then placed in the refrigerator for a half hour to forty five minutes while the vodka absorbs.
Dude, last night I went to the party and they had two watermelon titanic's. That shit is so good you can barely taste the vodka!
