does anyone know any swearwords that don't exist but should?

[GlitteringGrass]

Trying to write a fantasy book in an alternate world and the place needs swearwords. Anytime I see madeup swearwords they seem silly and twee. The word f**k for example, has a power inherent to it that would register with someone who just fell the sky. Its a kids book so don't worry about giving the meaning - but they should sound dirty and powerful. Thanks

suggit?

Battlestar galactica did this well by use 'frak'

Squaggers

Peebus

Nonk

Twump

Ds says "flattock!" He knows I can't tell him off because it isn't rude - but it sounds rude...

Twop chundler.

paggered

I don't know but I'm reading the BFG to my kids and there are some superb insults in there!

futtock?

Praggot
Skunt
Foff off
Piggar

I'm reading a book at the moment that uses rutting as a clean alternative to ducking but it's more YA book than children's book.

Ah new phone that has not yet learnt to swear. Fucking

DAR - VIT! in the Artemis Fowl series is fantastic. As is Frak/Frack in Battlestar Galactica. Hard short vowels. Play around with those. Or Google an Anglo Saxon dictionary. Those feckers knew how to express themselves - although I've heard fuck isn't Anglo Saxon after all ( wanders off on sweary tangent)

"Motherscratcher!" is currently in vogue among my students...

A hard consonant at the end seems to work best. G, K, T, P.

How about:
Scrak
Prag
Plig
Brok
Vrot
