Have you ever wanted to get/got revenge on someone?

Specifically someone who hasn't done something too crazy but they still get on your nerves? I'm open to hearing about any revenge story though lol.

I'm asking because I used to be friends this girl and basically found out she had been talking shit and spreading rumors about me and my friends (people she didn't even know) and she always loves to play the victim. She was telling people that one of my friends was racist, said slurs, and had videos as evidence (this bitch did not in fact). As for my other friend she had been making fun of her appearance. My friend was already insecure. Anyway, this girl likes to talk but obviously I wasn't going to let it slide when it came to my friends. I did my best to communicate with her and she totally freaked out so I gave her space until she was ready.
........
Tell me why she finally had the confidence when her "man" was next to her (they had been talking for 1 month), and mind you I've known both of them longer than they've known each other... THEY LITERALLY MET BECAUSE OF ME. Both messaged me at the same time saying I'm doing too much and being too defensive. MAN IDGAF STOP TALKING SHIT THEN AND LETS MEET UP IN PERSON TO TALK. They just kept going on about the same nonsense. Plus idk why HE had sm to say he wasn't even apart of shit. I blocked both of them and nobody is really friends with them anymore because everyone knows how fake she is but this grudge doesn't seem to be going anywhere. There's plenty of other factors but I'm afraid it would be too much to explain, this is just the summary. I hope you all know I'm holding back from talking sm shit about this girl.

Honestly this isn't as eventful as other stories where people are cheating or whatever but it still upsets me.
