zero. What is the point of pre-drinking? it seems completely dumb.
The point of going out is to drink beer that you can't get at home, and to drink in a social manner with your mates. The downside of going out is that you can't drink too much before you get a bit drunk and have to stop.
If you pre-drink, that is just less social drinking that you can do before you have to stop. Why would anyone pre-drink? Its completely ****ing retarded. Its like warming up for a marathon by doing a half-marathon.
Do you people also eat a big sandwich before going out for dinner?
