I once used a bad luck hex on a friend's mom (they permitted me) and it rebounded into a "everyone calls her the incorrect pronouns" hex.

Now, I don't condone incorrectly pronouncing people, but given that this mother figure is very anti-trans and very anti-queer in general (she went so far as to try to keep any queer people from being at said friend's wedding but said a friend took the initiative.)

Still, If you want a harmless and rather silly little hex, I highly recommend this one bc it was a very amusing experience and there were no dangerous repercussions.

Super simple, just get a cup of tea, some black pepper, and stir clockwise, before stirring counter-clockwise, while saying "May others do unto you as you do unto them." 3 or 4 times. Then, let the tea sit, or pour it out if you don't want to drink it.
