One of the most DUMB words ever, but besides that, means "DEal" and was popularized by the horrible song "What's the Dillio?" By MEst. I am ashamed to be a Mest fan for it.

this word originally meant, whats the deal, or whats going on. However, with new american slang, dillio now can be expressed as, whats the deal, yo?
Whats the Deal Yo?

A word popularized by the punk rock band Mest in their song "What's The Dillio?"

Its' meaning is loose, and can be what's the deal, what's up, what's going on, what's happening, etc.
"What's the d-d-d-dillio, dillio, what's the d-d-d-deal, deal..."

A term used by morons and their entourage. Also can be used in mocking those same morons.
No example can possibly prepare you for the horror's that will follow the use of this word.
