Some help with an insult for my story?

OK, so, I'm writing a story, and in the first chapter (which is what I'm working on now), the main female character, who is a Celtic Faery (although her first name is Greek), is getting kidnapped and taken away to the castle of the Vampire King. There are two guys kidnapping her. One is an Angel, the other is a Shifter. My problem is, I need to find an insult that sounds refined (and is in the English language), but applies to both of them.

I've tried the word 'barbarian', and that doesn't work because the Angel is a really refined guy. I looked up the word 'miscreant', but that didn't work. I also looked up cretin, and that didn't work. So, if I could get some help, I'd really appreciate it.
