Place a curse on your deadname so that when someone calls you by it they get a whole lot of bad luck/misfortune ✌
HOW DO I DO THIYI WANT TO DO THIS
Oh! Okay so first of all you can easily do a banishing on your deadname in a number of ways. This makes it get out of your life and be as far away from you as possible. I’ll list a few ways I like to banish on the go:
Write the name on a post-it note, go to a bathroom, attach the post-it note to a paper protective seat cover if you’re in a public/store bathroom (I prefer public bathrooms for banishings because it’s a liminal space and not attached to my own home and also typically industrial-grade toilets that can handle a lot of stuff like post-its, but it’s a tough climate for trans people and public bathrooms these days so BE SAFE and make the choice you are comfortable with) and then flush the toilet and the seat protector and attached post-it away. Otherwise you can just flush the post-it anywhere or use any paper. You can also write directly on a protective seat cover if that’s feasible. I keep pens on me at almost all times. Anyway running water is a classic banisher and that’s what flushing produces, and I find it a good modern replacement for a river. And it’s nice when public bathrooms can work FOR trans people, you know?
Otherwise I tend to use trash magic/trash witchcraft (I have a bunch of posts in that tag on it plus WIP excerpts from a book I’m writing) for banishing, and it’s along the lines of the above: write name, dispose of it. Chuck it in the trash. Public trash is great because it’s far from where you live and it’s already out in the world. It’s gone now, it’s out of your life. A variant is using Pokemon Go to delete stuff from your life.
If you want to curse people who use your deadname then it’s actually pretty simple. A lot of people make curse jars because then you can stick the ingredients in a jar and then bury it or shelve it so that the curse just stays somewhere safe and away from you and does its work while you go on with your life. You can also use a box. (You can even use something as small as an Altoids tin!) But with magic I encourage you to get frisky, follow your instincts, and do what feels right and just GO WITH IT. Anyway the easiest way to target, say, your deadname being said is to write the name on a piece of paper then draw a speech bubble around it to symbolize it being spoken. Then I’d stick that piece of paper in a jar/box, and put in some stuff that will make the person who says it feel pretty shitty. A classic is vinegar. Pepper, especially cayenne pepper, hot sauce, lemon juice, etc. Things you essentially don’t want in your mouth in large amounts??? Wasabi and Sriracha are also great candidates. You can also put in nails or even thumbtacks. Rose thorns/plant spines. Sewing pins are classic. Also broken glass. (Be careful handling stuff that can cut you!) Some people avoid ingredients that mold, saying that mold shows the spell has ceased to work. Others feel the mold increases the nastiness. If you use a cardboard box you’ll want dry ingredients.
And you can also throw in a zipper to keep people’s mouth shut in regards to your deadname!
Anyway, stick a bunch of awful punishing stuff in that jar with the paper and seal it up. You can seal the lid with wax if you’re feeling frisky, wrap it all with duct tape if you want though, it’s all your style and based on what you have on hand. Witchcraft for me is about using the means available to achieve the effects you need. Then put the jar/box away. Either a high closet shelf, or bury it, or find some place to stash it where it’s out of exposure to you but likely to remain intact for a good long time.
That’s the basics. You can always add or modify by using herb correspondences. The full moon was last night and it tends to have a 3-day range of effect so if you did this today, tonight would be a good time to charge the spell in the moonlight for extra power.
