Ruby, Gravscratch

Ruby: having serious sex with someone or laughing with their partner. 

To Gravescratch, goofiness generally implies a different tone, like when he’s playing with Blackspark in his alt. He largely prefers to be serious. Quiet amusement might happen during interface, but he doesn’t laugh easily and probably wouldn’t respond too well to a partner laughing at him, largely out of confusion and the beginnings of offense. Laughter is for playtime, interface is a different sort of play.
