Taken from one girl at summer camp, the phrase "Quiet Llama" refers to someone who is so tired that she or he is practically delirious. A Quiet Llama can be found laughing hysterically for fifteen minutes non-stop, randomly asking people "Would you like some felafel?", Placing their pink, see-through underwear on their boyfriend's hair, and generally not making any sense at all.
"I am such a quiet llama right now. I need a nap."
"God, did you see Cassia last night??? She was a total quiet llama"
"Please, don't call Molly when you're being a quiet llama. You'll never get off the phone."
"EMILY! ADRIENNE! I'M A QUIET LLAMA!!!!"
