You're A Moron

You idiot.

When someone proves their stupidity. This might be by playing a certain UnTrash (such as Play With Fire or Poke The Bear) or by not playing other UnTrashes (like Save The Day), especially if those UnTrashes were parti easy to play in the situation they apply to. Normally, others get annoyed by or upset with the playing character, but in Gleeful plays of this UnTrash, they might just laugh and jokingly tease the character.
