angry cinnamon roll

A cinnamon roll, but angry.
More specifically, when someone seems like an asshole or bitch, but deep down they're precious and everyone knows this. They might complain or yell a lot but they truly just care a lot about their friends. Often the victim of "You're so cute when you're angry!" or other similar phrases, which piss them off. Protect them anyway.

Karkat Vantas isn't mean, he's just an angry cinnamon roll.
