Used to describe something awesome. You can use this term to describe anything at all--as long as you are trying to describe that thing as awesome. You may use the term "Ill na na" however you like, even if it compromises the structure of a sentence. Ex: "Have the ill na na weekend"

More common examples:

"That blunt was some ill na na."
