Dog Mate
One who doesn't give you invites, leaves you out of things and is just generally a bad bloke. Should be constantly reminded of their poorly considered actions.
Dog Mate: 'Saturday night was great!'
You: 'Oh don't remember being invited to that, must've been lost in the mail'
You: 'Oh don't remember being invited to that, must've been lost in the mail'
