Flashtastic 

Originates from the DC Comic cartoon character - The Flash.

It is used to describe things that are superhumanly amazing, and awesome, pretty much THE best thing EVER.

It can also be used as an alternate form of the word "go" when playing games.

Typically it is best used to describe activities that you want kids to get REALLY stoked about.

Alright guys! This game of dodgeball is going to be FLASHTASTIC!

Ok kids, when I say "flashtastic" you are all going to spin around 20 times and then begin!!!

Those tater-tots are flashtastic. totally.

Flantastic 

When something is so amazing, that it rivals the consistency of Flan. In theory.

Lee: Dude, this essay is totally...totally...I can't think of a word!!!!!!!

Kerry: Flantastic.

Lee: Flantastic???

Kerry: Yes.

Lee: What!?!?! That doesn't make sense!

Kerry: It does if you have a 12th level intellect. Do you?

Lee: ...no, I don't know what that is.

Kerry: Then you don't have it, so shut up.
