A single can of Arizona Iced Tea. Called Dolla Holla because of its ability to be purchased for only one dollar.
Very popular among high school/college students because of its low price, high deliciousness, and large size (16.oz).
Person A: hmm. im really thirsty, but i only have one dollar.
Person B: grab a dolla holla! you get like 3 times the drink for for 1/2 the price
