A deeply, deeply committed commitment (like superglue), based on the tedious and lengthy process of consuming said fruit. You must be FULLY aware of the commitment you are making as you pick up the fruit, as lack of sufficient commitment will result in treacherous wastefulness.
You're pre-med? That's such a grapefruit profession! SNAP!

That's a grapefruit marriage, you better be willing to stick with it alllll the way, through the bitterness and sweetness.

The best living thing ever to have existed. Grapefruit is the Alpha and the Omega. It can never be called a "he" or "she", for the Grapefruit is an "It". Grapefruit is powerful, sexy, charming, seductive, outstanding, astonishing, unique, etc.The ultimate god of the fruits, Grapefruit is the most powerful fruit on earth and overpowers all veggies. It cannot be defined or explained, for Grapefruit is the unexplainable. The invincible. The almighty fruit of all time. Grapefruit has been, is, and will be. A veggie is a Grapefruit's enemy. It bows down at the throne of Grapefruit. Grapefruit is the most powerful thing in the world.
"I love Grapefruit. It is so powerful."
"Wow, that man is so handsome and charming. His name must be Grapefruit"
