Well it's an asian drink, obviously, it's mostly caught on over here in the West, but was out in the East far before it came here. I believe it started in Taiwan, with the basic, "Milk Tea" flavor.. basically, Iced Tea, with Milk and sugar.. very good, then later spawned various flavors, from fruits to like concoctions and what not.

They're basically Tapioca balls, so in essence balls of sugar. They're chewy to an extect of like.. noodles? if any chewier, they're made wrong >.> but yeah they're the new craze haha.. I suggest you at least try it before you knock it. I know a lot of "white" people that are all like.. wtf there's shit in your drink... nah just Frog Eggs.. >.> haha but it's seriously good.
