blow one's own horn

Boast about oneself

To blow one's own horn is to boast or call attention to one's accomplishments: He's always blowing his own horn about his sales numbers.

The image is of a herald announcing someone's arrival—except you're doing the announcing yourself.

Also *toot one's own horn*.

The phrase often carries a mildly critical tone, suggesting excessive self-promotion.
