A few years ago I was playing CAH with a friend who didn't like to curse, so he did word replacements. Two midgets pooping into a bucket. The biggest blackest phallus. Things like that. It made the game a little milder for him and added a new challenge for the rest of us to see who could give him the worst card. The card that won the night was "Rush Limbaugh's Soft, Poopy Body," and it haunts me to this day.
Thinking abt swears for worldbuilding and accidentially came up with a truly dreadful one i gotta share Spoiler: bodily waste And sex referenced, also just Gross "As useless as a used chocolate buttplug and twice as foul"
