What does chuff mean?
"Chuff" is a small word with several distinct meanings. In modern usage it is best known through its British informal form "chuffed", which describes someone who is very pleased or delighted — as in "she was absolutely chuffed with her exam results" — and speakers frequently amplify it with phrases like "well chuffed" or "chuffed to bits". Separately, "chuff" serves as a noun and verb for the rhythmic puffing exhaust of a steam engine, so that an old locomotive can be said to go "chuffing" along the line. A third, now archaic sense denoted a person with swollen or chubby cheeks, and in earlier centuries the word could even refer to a miserly, churlish individual. The delighted sense carries a warm, cheerful connotation and is a hallmark of casual British conversation, though it remains uncommon in North America, where it may puzzle listeners. Its blend of everyday warmth and railway nostalgia makes it a distinctive piece of English vocabulary.

In Britain, saying you're "well chuffed" means you're delighted — and the word may ultimately trace back to someone's cheeks puffing up.

Etymology of chuff
The history of "chuff" is genuinely murky, and dictionaries differ on its origins. The word appears in English by the sixteenth century in senses connected with swollen or puffed cheeks, and lexicographers have suggested links to other words describing swelling or heat, though no lineage has been established with certainty. The modern British sense of being pleased or delighted developed later, likely from imagery of someone puffing up with satisfaction or pride, and became widespread in colloquial speech during the twentieth century. The steam-engine sense arose naturally once engines themselves began to "chuff" audibly.

How chuff is actually used
The delighted sense is strongly associated with British English and almost always appears as "chuffed" rather than bare "chuff"; intensifiers like "well", "dead", and "made up" commonly precede it ("dead chuffed"). In American English the word is rare, and listeners may be unfamiliar with it. The steam-engine sense is descriptive and largely nostalgic. The older "chubby-cheeked" sense is obsolete outside historical dictionaries.
