I remember being in 5th grade, and there was a girl I had the biggest crush on. She was really sweet and nice to me when we were playing alone outside together, she even let me lick her armpits a few times... but when her friends were around she would pretend like she didn't know me. One day she pushed me as I was going to give her a hug in school, and made me look stupid. So I got revenge.

I filled up the super soaker that had like two large bottle reservoirs, forgot the model, maybe it was a 200 or something, and for an entire week, I would pee in the bottles. When she came and knocked on my door to play outside, I grabbed the super soaker, and she thought it was obviously just water. This time she went to put her arm around me and I punched her in the mouth, and when she was on the ground I squirted her entire face and her clothes with my peepee potion. Whenever she would scream, her mouth would open wide and I got a ton of it in her mouth with accurate squirting.

Needless to say, she avoided me forever after that. She deserved it though.
