Blow your own horn


Meaning
This idiom means to boast about one’s achievements, skills, or qualities, often to gain recognition or impress others. It suggests self-promotion, sometimes with a hint of arrogance, but can also be used positively to encourage confidence in sharing accomplishments.
Origin
The phrase comes from medieval Europe, where heralds blew horns to announce important figures or events. By the 16th century, it was metaphorical, with a 1576 text by George Whetstone using ‘blow his own horn’ to describe self-praise. In 19th-century America, it gained popularity, especially in journalism, as seen in Walt Whitman’s writings. The variant ‘trumpet’ emerged later, but ‘horn’ remains more common, reflecting American individualism.
