Predrinking 

V. - Act of Drinking alcohol before you go out to the club to maximize your fun at the club while spending the least amount on extremely overpriced alcoholic beverages... cause a beer at home is like 60 cents... a beer at your favorite night club is like 6 bucks... (dont drink and drive)

"Hey Fred, predrinking starts around 6 at my house... be there!"

Alternatively, can refer to drinking before attending an event where alcohol and/or drunkenness is prohibited.
