Not that I'm pro curses, but I had enough people asking for Irish curses so I put a few in the quotes section. Here is one I'm sure will get your enemies mad. (???)

"The curse of the wretched and the strong on the one who gave Tattheration to him for a mule"

Whoever put me into impotent grief And took my white tom-cat in secret from me.May the mice come in waves as his company and the rats from the kiln give him the pursuit

May the snails devour his corpse And the rains do harm worse May the devil sweep the hairy creature soon!

Or if be born may he not be like a Christian.A pigs snout on him and the mouth of a sheep.A beak of a duck that could dredge in the sludge. Lest he be a hangman that would hang the people.

Since you stole the sheep,you lying spoiler into hell I wish you to be tormented- In the depths of the whirlpool with Oscar blowing And twenty-one demons each tearing you asunder

No butter be on your milk nor on your ducks a web.May your child not walk and your cow be flayed. And may the flame be bigger and wider which will go through your soul than the Connemara mountains if they were on fire

He's as greedy as a sow As the crows behind the plough- The black man from the mountain,Shauneen Roo

May your hens take the disorder(the fowl-pest),your cows the crippen(phosphorosis) and your calves the white scour! May yourself go stone-blind so that you will not know your wife from a hay-stack!

May the seven terriers of hell sit on the spool of your breast and bark in at your soul-case

Woe to you you dirty fellow You've filthied me!
