Fun fact, in the Gypsy language (Romani) I speak we really don’t use swear words. Of you want to say something like go to hell to someone you curse them out in a way similar to this.
“May I never eat at your wedding”
“May you always step in water with new socks on”
“May your future kids be just like you”
And the worst one “May your entire family dine with the Devil/ Turn into the devil”
There’s many variations most often depending on country of origin,this is just a few examples.
