Minecraft What does "DX" in BaseballBatDX represent?

So remember that old game What does "HC" mean? Well I'm bored so I decided to make it harder this time.
I had an old name call BaseballBatDX. Anyone remember?

Anyways so the objective of the game is to find out the meaning of DX and why I put it in there.
There is also a competition to think of a name for DX for example:

Person 1: I have a good name! D=Dude X-=X-ray

So here it is to sum up

• Make up a name for DX
• Find why it's called DX in the first place.

I will give hints at the end of each week.

Good Luck!

 

Does it stand for deluxe?

 

DX looks like a sad face

happyface: XD
sadface: DX

 

Actually it kinda does. First post of the game and already got it.

But besides that, keep them posts going!

 

Deluxe Xeno.

Probably in the first place cause it looks like a sad face like what @Bilbo said c:

 

Deluxe XenForo

 

Di XonCider

 

Nice! But not really appropriate is it?

Hint 1: It does not represent a sad or happy face. Why would it if it's in capital? XD DX
