Purple Fweem

An extremely sugary purple drink made by the character Kevin from the Crabgrass comic series. Unofficially known as lean for kids, the high-fructose drank is so potent that it causes any first-timer to scream "FWEEM!" at the top of their lungs.

Kevin: "Check it out. Seven kinds of soda, two cups of sugar, and a whole pack of Brainies™ candy!"
Miles: "It's so THICK!"
Kevin: "I call it Purple Fweem."
Miles: "That's a weird na- FWEEM!"
