Never knew that Jake. Something new everyday :o)
Although I had alot to drink at weekends my friends and I were never once abusive to anybody - physically or verbally.
So it isn't the drink that makes people agressive, I think they are already agressive but the drink makes them worse or act without thinking. There were a group of lads who were known to be aggressive and most people steered well clear of them, but these lads were always like this not just when drunk, the drink just made them worse!
