The Half-Hag Concoction
Half-hags are nonsensical. They don’t know if they’re hags or not, so they’re ugly but act like they’re not.
Half-hags have rotten opinions about when to use salt and when to have sex on your period in order to gross out non-hags and Christians (pagans of course love blood).
If you see a half-hag, the only way to kill her is with a silver bullet, or any other type of bullet, fired at close range from a magnum or Winchester rifle, or at long range with any suitably powerful sidearm. Or with a knife, a club, poison, or by pushing her in front of a train...basically anything that kills a normal hag will kill a half-hag.
Half-hags love to make haggis, which is really just a dump with trimmings.
You may be able to detect a half-hag using a tall glass of frosty beer. If you look through the beer at a woman and she looks the same, she is not a half-hag. If she looks all blurry and super hot, a half-hag she be.
If you come down with a sore throat and a half-hag is around she will try and make you gurgle something. This is the dreaded half-hag concoction called “gurgle nut”, and is really the semen of her last victim.
Toss it in her face and she will devolve before your eyes into a run of the mill moccasin-wearing, Escourt-blue-smoking, flannelette-shrouded pogga.
Poggas are easily identifiable by their smell and awful hair. They often live in caravan parks.
