Millennium 

A version of the drinking challenge, Century Club. The rules are similar but every 10th shot is liquor instead of beer. Thus the total amount drunk is 90 shots of beer, and 10 shots of liquor. This must be done in the time span of one hundred minutes. Made popular by students of Queen's University.

'Hey bro, wanna do Century Club?' - Bro

'Don't be a pussy man, let's do fucking millennium!' - Alcoholic Bro

Millennium gangster 

People between the ages of 15-25 who act extremely hard for white suburbanites. They act as if they are "about that life" but in actuality they have most likely never been in a fight. The hard knock life they portray is a complete fallacy and is most likely an over compensation for a lack of self-confidence. They will continue to make Facebook posts about people who are "bout to catch wreck", however when they are confronted face to face with the situation, they will immediately try to "talk it out"'

Did you see the millennium gangster in the store wearing the snap back and skinny jeans start crying when the lady caught him stealing and told him if he didn't put the stuff back she was gonna get her son to beat his ass.
