One that gets horny from fruit.

Similar to a fruitbat, a fruitfuck is a guy who is known to be homosexual to the point of having gay sex. It's actually short for 'fruity fuckstick,' which describes a condition under which the penis only gets hard when it's involving fruityness.
That guy is such a fruitfuck.
