The only thing I've heard this year was when they scored 19 runs against the Dodgers, Dave Roberts made a comment after the game along the lines of "not to reopen old wounds, but it really seemed like they knew what pitches were coming."
As a Dodgers fan, I obviously hate the fucking Astros. Their fans will tell you that it's because we lost to them in the World Series, but they're wrong. We lost to the Cubs in the NLDS the year before that, and the Red Sox in the World Series the year after. I don't hate either of those teams (even though the Red Sox have similar cheating accusations from that year). It's because the Astros players and fans were a bunch of unlikeable fuckheads.
