The quality or state of being groovy; coolness or excellence with a funky quality.
From 'groovy' + the abstract noun suffix '-ness,' which converts adjectives into nouns describing qualities. Common in English for creating abstract nouns from descriptive words.
Grooviness is hard to define precisely—which is why slang survives! It captures a vibe that 'coolness' alone doesn't convey. The moment people could scientifically define it, it would stop being groovy.
