To piggy back off of Kearly's thread, what college teams do you really dislike?
There are quite a few NFL Teams which I really can't stand and are easy to hate (Cowboys, Jets, Raiders to name a few), but its not as easy for me to hate college teams.
I love beating UW, but I don't really hate them and generally root for them in most of their games.
I really dislike Notre Dame, don't even really know why, just always have. Also have a pretty strong dislike for Texas, seems like they get 5 star recruits and turn them into 5th round draft picks, plus I think they have the most entitled and arrogant fan base.
Ohio State would probably be pretty high on my list too, not because I dislike them necessarily but because I really dislike Urban Meyer. Same would go for USC as long as they keep Kiffin around (although as a rival I hope they keep him around for a long, long time!)
But I think my most hated college team is Boise State. I'm sure its partly because they beat my Ducks the last two times they've played, but mostly its because I absolutely HATE that damn blue field.
