A colleague of mine who works in a hall nearby told me that the other day at the end of the school day when the hallway was crowded with kids, some kid yelled into his room something like "Mr. --- sucks!". I thought that was inexplicable because this teacher is really good. He is pretty friendly and approachable and has a decent rapport with his students. I worried about the likelihood of such a thing happening to me, especially as it seemed completely unmotivated. Plus what if it happened while a class was in session? That would be embarrassing and there's no way to catch a kid when they do that. I thought this might be on the order as the same kind of behavior as when a kid says "--- you!" to a teacher in their face (I've heard stories about it) or shows other signs of disrespect. Is it enough to simply discipline a couple of kids that they would be so obnoxious or if they failed a class getting upset and blaming the teacher, thus feeling justified about saying rude things? What kind of experiences have you guys had? On the other hand I can think of teachers who kids would never say rude things to because the teachers are so mommy-ish.
