swear words, insults and other forms of swearing.

There’s a wide variety to pick from, some swears work best as insults, others as exclamations and others as expressions of disappointment. There’s also a range of styles, some work better in a fantasy setting, others in a futuristic setting.
I refrained from using real curse words to create new ones in most cases, but you’ll find a few here and there.

Withered bird brain!
Grime reaper!
Good gravy!
Son of a troll!
Swizzle sticks!
Sweet onions!
Monkey disco!
Whack a holy moly!
