look up any word, like pussy:
 
1.
A 2L bottle of alcohol, usually a cooler. Usually people just drink right from the bottle, because that's how thugs roll.

2.
A whopping 1.18L of nasty ass 8% beer (also known as Big Bear, Colt 45, Black Bull). Can be picked up at the nearest liquor store for 5 bucks.
I went to the liquor store to buy a thug jug.
