Activity that is DRINKING BEFORE DRINKING. Usually to drink before going out to a club or party. Sometimes the reason for pre-gaming is to get a buzz started before arriving at the destination, and sometimes to spend less money trying to obtain a drunken state at the bar or club. You don't even have to change locations to consider it a pre-game. It could be getting a couple drinks in before your friends arrive at your house to drink. But it always is drinking before an event that includes drinking. You can pre-game by yourself or gathering with friends. But the gathering must change in order to count the initial gathering as a pre-game. Such as the group of you going out after the pre-game. It is not pre-gaming if you get together to drink and do not change something such as A)location or B)several members of the group. That is just extra drinking time.
