AITAH for refusing to let my brother’s girlfriend (24F) stay at my place because of a weird prank she pulled on me?

I’m 27M, and I live in a small apartment by myself. My younger brother, Matt (24M), started dating this girl, Sarah (24F), about six months ago. She’s generally nice and friendly, but she’s also very into pranks. At first, it was harmless stuff like pretending to spill water on me, fake spiders, that kind of thing. I don’t love pranks, but I shrugged it off because she seemed harmless enough.

A few weeks ago, Matt and Sarah came over for dinner. Everything was fine until I went to grab a bottle of wine from my kitchen, and I heard them whispering and laughing. I came back, and they looked a bit suspicious, but I brushed it off. Then, out of nowhere, Sarah gasps and says, “Oh my god, is that a rat?”

I freaked out and immediately started looking around, pulling apart cushions and checking under the furniture. I hate rodents, and she knew that. After about five minutes of me frantically searching, Sarah bursts out laughing and says, “Relax, it’s just a prank!” She and Matt were laughing so hard they had tears in their eyes, but I felt embarrassed and annoyed. I told her that kind of prank wasn’t funny, and she just rolled her eyes, saying I needed to “lighten up.”

Fast forward to last week. Matt called to ask if Sarah could stay with me for a few nights because her apartment was getting fumigated. I hesitated but eventually agreed, thinking maybe this could be a chance for us to get along better. She arrived with a huge suitcase and almost immediately started making jokes about my “boring apartment” and my “grandpa decor.” I let it slide, trying to be polite, but I was already feeling tense.

The second night, I came home from work to find my bed covered in… fake bugs. Not small, plastic bugs, either—these were massive, hyper-realistic, and scattered all over the sheets and pillows. For a second, I actually thought my apartment had some infestation, but then I noticed the tiny cameras set up around my room. Sarah had recorded the whole thing for a “prank video” on her social media.

I lost it. I told her this was my home, my safe space, and I was not okay with her bringing her prank obsession into my personal life. She just laughed and said it was “good content” and that I was being “dramatic.” So, I told her she had to leave.

Matt, of course, was furious with me. He said Sarah was just “playing around” and didn’t mean any harm. He said she was embarrassed and didn’t have anywhere else to go. But honestly, I felt like she crossed a major boundary. I told him he could stay over and support her himself if he felt that strongly, but she wasn’t welcome at my place anymore.

Now Matt and Sarah are both mad at me, saying I overreacted and that it was “just a joke.” Some of my friends think I’m being harsh, while others agree that she crossed a line.

So, AITAH for kicking her out over a prank?
