A dated and largely archaic slang phrase meaning to speak loudly, boisterously, or with excessive confidence — often implying the speaker is showing off or talking more than the situation warrants. Typically used in early 20th-century American slang. The connotation is mildly negative, suggesting someone who is blowing hot air. Rarely encountered in contemporary speech, though it may appear in period fiction or historical dialect writing.

The old-timer would air off at the bar every Friday night, retelling the same three stories to anyone who'd listen.
Origin: Likely from the imagery of "airing" one's voice loudly into open space; the phrase parallels expressions like "blowing hot air" or "airing one's opinions" with an added sense of volume and bravado. Editorial expansion authored on Slangora (model-assisted, hedged).

A dated slang phrasal verb meaning to speak loudly, boastfully, or at length without much concern for the audience. The air element suggests ventilating one's views into open space unchecked. Now largely obsolete in everyday speech, though the concept survives in the phrase airing grievances. Rarely used in contemporary conversation outside dialect or historical contexts. Not likely to be understood by most modern speakers without explanation.

He would air off about the landlord to anyone in earshot, whether they wanted to hear it or not.
Origin: From air in the sense of broadcasting or ventilating; the phrasal construction adds directional force. Editorial expansion authored on Slangora (model-assisted, hedged).

Register: archaic, historical. Almost never used today; you will find it only in older texts, dictionaries of dialect, or historical writing. Avoid in active vocabulary. A common learner mistake is using the word in a register it does not fit, or assuming a single global meaning; native speakers immediately notice when slang appears in formal contexts, so always check the surrounding register before producing it yourself.

(intransitive, slang, dated) To speak loudly.

For parents

Air off means: To speak loudly.. It is informal slang, fine in casual speech but not suited to formal contexts. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. If your teen uses it, context will usually make the intent clear. A short, curious question about where they heard it is usually all that is needed to know whether to follow up.

For ESL learners

air off means: To speak loudly.. Register: dated, informal. Suitable only for casual conversation, chat and social media. Do not use in business, academic or news writing.
