Feb 19[os-ten-tey-sh_uh_ s]
Definition:
Characterized by intending to impress others with obvious and conspicuous show.
Example of usage:

Comments:
This word is a synonym of “showy” and can be incorporated to more aptly describe someone’s behavior rather than saying that they are “showing-off”, as is more commonly done.
