How it's used
This term carries a strong sense of annoyance toward someone who is being overly arrogant or full of themselves. It is specifically used to describe verbal posturing or showing off through speech rather than just general conceited behavior. The reduplication of the final character adds a playful yet dismissive tone to the criticism.
Examples
He is always bragging, it is so annoying.
Don't be so boastful, it is better to be humble.
