Natty is also slang for 'natural' as in the cheapest type of beer on the market. This beer mainly comes in the form of 'natty ice' or 'natty light' and has a flavor somewhere between water and piss. Despite its many, many downfalls, it does function to get you drunk if you drink enough of it. At most frat parties, the keg is filled with natty, since it is so cheap. Natty cans are usually found near redneck or frat boy hangouts. This beer is basically as cheap as soda.. getting a 12 pack costs about as much as getting one beer at a bar. But its not worth it..
