I do not think it makes you a dumper but I do not understand your disdain for that 'catch phrase'. I have never said it or typed it but I think it kind of funny. Seems like a polite way to say F-U. I rarely come to TNet anymore, so maybe it is over used on here.
Personally, I thought it was brilliant and funny when Swinney said that and if that bothers you then that's your problem. What really does sound dumb is a question like, "Does it make me a dumper"....What are you, like 14 years old? Get off your parents computer and get back to your summer reading list, son.
Not me, I like the "in your face" response. I don't like a little whiner like a steevie boy spurrier who sucks through his teeth when he talks. He is the kind of guy that would hit you in the back and then run to get behind his teacher so he wouldn't get his butt kicked. By the way, I don't tweet.
