A character from Mad TV, stereotyping fast food workers from the hood using King Burger-- a spoof on Burger King-- as the setting. Taking orders, she personifies the urban ghetto laziness running through society: refusing to take an order for a cookies and cream shake, calling "sah-kurity" on customers with difficult orders, appeasing management, and doing minimal work.
Pronounced either Kwee-Kwee or Kwa-Kwa, it is a common response to when somebody (usually a guy) says or does something gay.

Mike: "What should we do tonight?"
Ben: "I dunno, I'm kinda bored. Maybe we should go stargazing..."
Mike, Mark, and Jake: "Que-Que."
