Ha! Wait a minute...
You think someone is joking around nicely, but then you catch on that they're either making a bad joke or they're being mean to you
You think your buddy is just teasing you, but then you realize he was being a total jerk
You laugh at your teacher's joke, only to find out it was a way to humiliate you
You think your sibling was just being silly, but they were actually making fun of you
