Not so much a drinking game to warm up with but a few drinks, me and my mate used to try and come up with new drinks (mixed up) and see how fcuked we could get on them. That and they had to be odd drinks.
We got to the point of mixing half a pint of the cheapest and foulest cider and then mix it with the cheapest vodka we could find. Not much could be re-called after that lot. I guess it kind of became a game, trying to find the cheapest sh1te about and seeing if we could mix it all up and not throw it up.
But i don't drink much any more and very carefull what i drink these days (also lies through back teeth but thats the official reply to other half and the docs)
