Don't get me wrong, I'm not trying to single out OC SC fans, I've seen fans of other MLS teams that are obnoxious.
Case in point: I went to the NYC FC/NY Red Bulls game in NJ recently, and, at half time, as I was walking towards the rest room, this drunken dude in head to toe Redbulls gear came up to me, and the following convo ensued:
Redbulls Fan: (Slurred) Yo bro, your team's losing! My team's winning!
Me: Yes, I know, it's a good game though...
Redbulls Fan: Yep, good game for the mother fucking Redbulls, bitch!
Me: Yep, well, nice meeting you bro....
Redbulls Fan: (As I was walking away, screeching at the top of his lungs) NYC FC FUCKING SUUUUUUUUUUUUUUUUUUUUCKS!
