The idiom "toot your own horn" means to brag or boast about yourself, your accomplishments, or your abilities. It is used when someone talks about themselves in a way that is meant to impress others or make themselves look good.
For example, if someone says "I'm the best player on the team and I always score the most goals," they are tooting their own horn. It can also be used in a negative way, when someone is being too proud or arrogant about themselves.
It's important to remember that while it's okay to be proud of your achievements, constantly bragging about them can be annoying to others. So, it's best to be humble and let your actions speak for themselves.
