I think it's probably a mix of usually being an attractive older woman with a large ass in an authoritative position that isn't linked to incest, also probably because it opens the door to a lot of scenarios

Stuff like detention farts, them being given a laxative as a prank, using the student bathrooms, drinking a lot of coffee, farting during lessons, getting a teacher's ass in your face when she's helping someone out (basically has happened to everyone at least once), etc. that makes them so popular

Old Internet story of a woman who would drop massive shits and would use scissors to break them up so they don't clog the toilet or something

It's been a while since I actually got told the story
