What does bubbly mean?
Bubbly functions primarily as an adjective with two related senses: it can describe a liquid full of bubbles — such as fizzy drinks, sparkling water, or champagne — and, by metaphorical extension, a person whose manner is lively, cheerful, and enthusiastic. A bubbly personality suggests warmth, energy, and sociability, making the word almost always complimentary when applied to people. In informal usage, particularly in British English, bubbly also serves as a noun meaning champagne or sparkling wine, as in 'a bottle of bubbly'. The word derives from 'bubble', tracing back through Middle English. Its connotations are light, festive, and upbeat: whether describing carbonation at a celebration or an effervescent character at a party, bubbly consistently evokes liveliness and good spirits. It is common in everyday speech and journalism but less suited to formal writing.

(informal) champagne or sparkling wine.

As a noun meaning champagne, bubbly is typically treated as an uncountable mass noun; a countable plural is rare and informal.

In British pubs and parties alike, ordering 'some bubbly' instantly means champagne — no other word does that job so cheerfully.

Etymology of bubbly
Bubbly is formed from 'bubble', a word of uncertain ultimate origin attested in Middle English, combined with the adjective suffix '-y'. It developed in English from the literal sense of something covered in or full of bubbles, later acquiring the figurative sense describing a lively, effervescent personality, and eventually the informal noun use referring to champagne. Its cognates are essentially the various derivatives of 'bubble' itself within English rather than words borrowed from other languages.
