Millennials will talk about four loko the same way their parents talked about lawn darts
Wow, as a Millennial, I must've totally missed the memo on this stuff. Never heard of Four Loko or energy beers at all... sounds disgusting.
In the US, they fall under the same legal category as beer, which is "malt beverage", but beer is just one type of malt beverage, drinks like Four Loko are another.
They're closer to drinks like "hard lemonade" or "hard tea", which aren't beer. They're made by adding malt liquor to some flavored drink.
