Agreed, some of the swearing comes from me.
Yes, I have a potty mouth. I am the girl whose father got tickets in the next section when we met up in Wisconsin because he didn't want to be associated with what I might say (although I was pretty restrained that game, since we won.) I even had a little problem with swearing on this here message board when I first started posting.
I'm not that bad anymore, but I have plenty of insight into the mind of a foul-mouthed fan. Well, one kind of foul-mouthed fan. I can't claim to understand the crabby old fans that curse at the refs, but they're old, so what can you do? But I guess I didn't really care what other people around me thought. Like, anyone who would be offended by swearing was a huge loser and totally lame. Sadly, the only real cure for this is getting older and wiser. And sober.
