A very annoying and stupid phrase used to describe someone or something very cool.
- "Dude, this kid I know is mad chill..."

- "What the hell is with all this 'mad chill' crap that everyone keeps repeating?"

- "Well, uh, it's just a new thing everyone is saying..."

- "Can you think for yourself for once and not use such a stupid phrase and stick to something that isn't so retarded?"

- "Dude, you're being an idiot..."

- "'Dude', please don't call me 'dude'... and I'm not the one whose saying 'mad chill'"

- "..."

- "That's what I thought..."
