Heathenry

To perform an act so grotesquely wrong, it is classified as heathenry.
Also kept to describe the worst things in the world, a descriptor for awful things like the word 'moist', pineapple on pizza and walking around outside with wet socks during rain.

"Did you see the latest fad out where all guys are piercing their ballsacks with sparkly jewellery and walking around with them hanging out of their jeans? Absolute heathenry".

Also "you thought pineapple on pizza was bad? I just ate strawberries and sausage gravy on a pizza!" "What, why? That is absolute heathenry behaviour"
