Sammy

Dean: House rules, Sammy. Driver picks the music, shotgun shuts his cakehole. Sam: You know, Sammy is a chubby 12-year-old. It's Sam, okay? – Dean and Sam, 1.01 Pilot

Dean's nickname for Sam is Sammy, generally used either for teasing or in moments of great emotion. While Sam initially protests its use after he and Dean first reunite in 2005, it becomes clear it has as much meaning for Sam as it does for Dean when Gordon Walker uses it and Sam retorts "He's the only one who gets to call me that."
