I'm in need of some derogatory terms for nobles for a story I'm writing, something for a fantastical medieval based world. The more the merrier!
a derogatory stereotype for someone with an aristocratic background or belonging to the landed gentry, particularly someone who exudes an air of superiority.
You haven't specified why the derogatory term(s) would be applicable.
Is it because the nobility is a pampered, ineffectual class which gives itself airs?
inbred twit, mincing fops, jaded halfwits, privileged ninnies, pampered parasites
On the other hand, are they competent rulers who run roughshod over their subjects?
callous oppressors, bloody-handed bastards, sadistic scum, privileged tyrants, sanctimonious despots
