A shitty, extremely bitter beverage which I have no idea how it so popular. If you want to drink real beverages, go for expenive red wine, brandy, or rum.
Brands like Bud Light, Miller Light, Golden Biersch, Heineken are all beer (there are more brands, but I can't think of any others right now).
A great tasting beverage that can lead to getting you buzzed and drunk. People have different tolerance levels making it hard to detect who is drunk or not. There are different levels of drunk. There's the standard level of 'drunk', 'more drunk' and then it skips all the way up to 'shitfaced'. When at the level of 'shitfaced' you tend to puke/pass out/not remember anything. It can be fun until you end up in the middle of nowhere with your shirt and shoes missing. Some beers are great to enjoy but there's always a reason people are drinking, and that is to get to the level of 'shitfaced'.
