How does you being 12 and having a small dick have anything to do with your team? I get that Seattle fans love calling themselves the 12th man, but that's not original to the Seahawks and there's certainly no indication that he was using it in that context here. I feel like you should know the order of events since you were part of it, but here's a recap.

He said

know how I know you've got a small dick

you're 12

I'm just as funny as you.

So you say

oh, you. you just hate 12-year-olds because since we've been alive your team hasn't won their division.

THEN he brings up your former NBA team, after you already brought teams into it. And wasn't bashing the team whatsoever just saying how someone who was 12 wouldn't even remember having the Sonics.

My, "division" is a mighty big word for such a young fella! Come over here, scamp. Lemme ruffle the ol' mop-top and recount stories of ye olden days.

A long, long time ago - before you were born - Seattle once had an NBA franchise and....

So then you respond again bashing his NBA teams

and that seattle NBA franchise that doesn't even exist anymore has a more recent NBA title than either of NY's two teams.

keep em coming though. you've got the people on your side.

Do you not see that you brought up teams first? Do you not see that his only joke was that you are 12. Even him talking about the Supersonics was only referencing the fact that a 12 year old wouldn't remember them. You were the one to bash him because his teams haven't won anything recently. He made a joke about your age because you seemed like a 12 year old (valid), so you make a joke about teams. Completely unrelated.
