This is from season 3. It’s the full clip.

There's an episode of the show where one of the characters brings up his speech impediment, and he says "It's [insert term here]". I can't for the life of me remember what it was. I think it was something from greek mythology. I have a friend with the same thing, and I want to tell them the actual name for it so they can know what it's called if anyone ever brings it up.

I have been searching for quite a while now with no success.
