Watermelfunction 

When a man about to have sex with a girl (or guy if you're into that kinda thing) turn out the lights , penetrate him/her, ejaculate, turn out the lights, and find out it was a watermelon the whole time.

"Tommy WHAT THE FUCK ARE YOU DOING!"
Tommy: "Well looks like we have a case of Watermelfunction."
