A Liverpool Football Club supporter, brother of Blogger: From the point of view of an Arsenal fan who subscribes to Arseblog. Blogger's brother (being a Liverpool fan) allegedly smashed Blogger's Arsenal mug when they were kids. Mugsmashers is now a common collective term used to describe Liverpool football club, its supporters and the city in general.
"Let's beat those mugsmashers!"
"Damn those mugsmashers for nicking that draw"
"I'm off to Mugsmasher Land for a bit of a do." (spurious)
