if they get offended theyre "so middle school"? wow. obviously there's different tolerances amongst different people for using slurs amongst strangers. personally I'd avoid that term, especially as a cyclist in the midwest, where that's hands down the most common "insult" shouted by passing morons in trucks. but then, Im also not one to have bike path time trials with dudes on huffys either so maybe Im coming at this from a different place.
