When used in the expression "to be a grapefruit" it means being a third wheel, the spare part, feeling left out or excluded, as is the case if you go out with a group of couples.
It turned out to be a double date--James was supposed to come along but when he found out that both my and John's girlfriends were coming along, he decided he didn't want to be a grapefruit.

The act of getting so lonely you carve a hole in a great fruit, heat it up for 30 seconds, and masturbate with it.
"Oh my god this grape fruit is amazing!"

A food of deception. It is not a grape, and doesn't taste like a fruit. It is obvious that grapefruit is a mere vegetable in disguise.
All warfare is based on grapefruit-like behavior.

Word used by men to get off a boner. Used by Kyle in Kyle XY.
Dude I felt like such an idiot in math. I got a boner, so I had to scream "GRAPEFRUIT!" to get rid of it.
