going over to some friends, we usually find some nation then theme the evening round that by (poorly) cooking some of their traditional dishes, (excessively) drinking their traditional drinks & (mockingly) simulating their new year traditions. Finally at some point roughly around mid dnight we let of a load of fireworks and marvel how we havn't maimed ourselves.
Did Mexico a few years back, drank a load of Taquila, Corona etc and ate 12 grapes on the strikes of midnight while wearing huge hats - classy!
