something with a superbly fantastic taste that leaves you so speechless, you start talking in Dr. Seuss-like words; tending mostly towards chocolate-related foods; originating from Willy Wonka and the Chocolate Factory
"How's that chocolate bar?"
"Ohhh, it's scrumdidilyumtious!"
"How was your meal?"
"It was scrumdidilyumptious."
A word that can positively describe any given type of food, a word that is above all others.
So, instead of saying:
That was the best pizza ever!
You wouldsay:
That pizza was scrumdiddlyumpcious!
Jeff: Yo dan, Im hungry, make me some food!
Dan: Ok, want me to make you a bagel?
Jeff: Yes! Your bagels are scrumdiddlyumpcious!!
