Chuffed
What it really means
Very pleased and proud about something. People often say "chuffed to bits" to mean extremely pleased. It is the opposite of "gutted".
Context, tips & common mistakes
Chuffed means pleased and quietly proud — 'chuffed to bits' or 'well chuffed' for the strong version — and it is the approved British way to express happiness about your own success without boasting: 'got the flat — pretty chuffed, to be honest.' Understatement rules apply, so 'quite chuffed' delivered with a grin usually means delighted.
Use it freely: it is warm, informal, universal across regions and generations, and never rude. Congratulating someone else, mirror it back — 'you must be chuffed!' invites them to enjoy their win while staying inside the modesty rules. Its opposite number in the disappointment column is 'gutted', and between them the pair covers most of British emotional life.
