look up any word, like pussy:
 
1.
A completely natural fruit juice with a splash of sparkling water, cleverly disguised in a rad looking bottle or can so you feel like you're indulging in sugary pop, when all you're doing is drinking juice. Relatively unknown due to the fairly selective selling of it and a slightly absurd price. (Sold in Whole Foods, coffee shops, Chipotle, ext.) Most popular with teens, especially vegetarian, "Go Green!" types and scene kids. Also popular with health freaks but generally enjoyed by anyone sane enough to try it. UNDENIABLY DELICIOUS. Flavors include: sparkling pomegranate, apple, grapefruit, blueberry, clementine, peach, and blackberry.
Persephone: What's your favorite flavor of Izze? Mine's Sparkling Pomegranate!
Tiffers: Um, what's Izze?
Peresephone: Look it up on urban dictionary. *walks away shaking head with pity*
