D12 Rapper fatally shot in the head in a Detroit nightclub on Tuesday.
"According to police, evidence indicates 32-year-old Proof (born DeShaun Holton) fired the first round in Tuesday's fatal shootout inside the CCC Club, located along East Eight Mile Road in Detroit's East Side. But before he pulled the trigger, eyewitnesses claim, Proof pistol-whipped Keith Bender Jr., who fell to the floor, at which point police claim Proof shot him in the face. Proof was then fatally shot by another man — once in the back of the head and twice in the chest."

The term comes from the practice of adding gun powder to an alcoholic liquid and putting a match to it. If the powder ignited then the drink was "Proven". Now is used to show the alcohol content of a beverage. It is calculated by multiplying the % of alcohol in a drink by 2. Ergo, the max proof of an alcoholic drink is 200.
Despite the beers lower proof than the Everclear, if you beerbong 13, you still pass out.
