Definitions
A warm, slightly old-fashioned English word meaning friendly and closely acquainted — the kind of matey, comfortable closeness between people who know each other well. If two people are being chummy, they're bonding, laughing together, and acting like old pals. It can be used approvingly ('they've become quite chummy') or with a mild edge of suspicion ('they're very chummy all of a sudden'). The word has a cosy, slightly round quality to it — nobody says 'chummy' while being serious, and that's sort of the point.
The new colleague and the manager were already getting very chummy by the end of the first week, lunching together every day.
