headcanon: Damon spends a lot of time thinking up new Bon-related puns/nicknames, but he only slips them into conversations when Bonnie can’t quite be sure if it’s intentional or not, just to mess with her (ie. “Bon appetit!” in 6x01).

He keeps a running list in his head:
sweet cinnamon bon
bon-afide truth
bon voyage
jo has a bon in the oven
working his bons off
bon jovi
bon iver
