I am just tired of your aristocratic arrogance. Let's compare who got more behind the mouths of ours. Yes or no? Who is talking out of his ass here? I am ready and prepared to get this wager set up. Publicly for everyone to see. The only one who is talking out of his ass is you. And only one is folding here. Loser!!!
Let me see if I can dumb this down for you. When someone is told to "back up" their mouth (as you're trying to phrase, albeit in a caveman-esque manner), it is to support a statement they have made. Show me the statement I made that you claim is false and I will back it up.
I'm not trying to back up statements you made.
