Phrase used at the end of someone's obnoxiously horrible story by everyone who heard it, in response to its pure stupidity. Almost always accompanied by claps and said in a chant, so it becomes:

"Grrreeaaaaat Story....Tell itttttt again!" (With one clap for each word)
Person 1: So yesterday I went to go get coffee, and it sounded really delicious, but the coffee shop was closed when I got there.

*Pause*

Everyone listening: "Great Story Tell it again" (chant)
