Mondo 

The quintessential word of the English language, mondo can be used as an adjective, adverb or a noun. It expresses general feelings of approval when used as an adjective, but when used as an adverb it can substitute the word "very." As a noun, it is used to generalize the mondo mentality. This word is best used in a rhyming phrase, such as "mondo like a condo."

"She's cool, but she sure ain't mondo!"
"That was mondo awesome!"
"You just can't handle this mondo!"
