YOUR X DOESN'T DESERVE

"Your X doesn't deserve a place in my Y, but it might make a good coaster for my drink" is a phrase that first appeared on 2010's Christmas Special "An Ishtar Family Christmas" of ''Yu-Gi-Oh! The Abridged Series''. The phrase quickly achieved a memetic status on the Kingdom Hearts Wiki IRC channel after the video was put up when Tabbeh was feeling everything around him seemed a little unworthy to him.

Origin
This phrase first popped up on the Kingdom Hearts Wiki IRC channel not too long after the aforementioned video was put up on YouTube. Quickly enough, it became a phrase that users DoorToNothing, Tabbeh, and various others began using.

Usage
When there's something that you honestly do not think deserves a place in a collection, party or project, just tell the person who gave you that that it's not worthy of becoming a part of it like so.

Here is one such situation in which it is appropriate to use this:

You and your friend are avid Pokémon players. One day, you and your friend decide to trade Pokémon. The first Pokémon you see in his party is this:

http://images.wikia.com/pokemon/images/3/3c/Dasutodasu.png -( hi, love me plz)

You honestly do not want this Pokémon. But you need it to complete your Region Dex. But you don't want it. You start, "Uh, bro, I need this Pokémon... thing to complete my Dex…" and your friend offers to trade this Pokémon to you when…

You blurt out "… but THIS POKÉMON DOESN'T DESERVE A PLACE IN MY PARTY, BUT IT MIGHT MAKE A GOOD COASTER FOR MY DRINK!"

Your friend is in stitches. Garbodor, however, cries digital tears of nonexistence.

Basically, as explained before, if there's something you don't want as a part of a collection, reject like the cool kid who rejected Garbodor.
