Showing off, but make it culturally acceptable.

means A public display of things (or talents) for others to look at, judge, or admire.

from From Latin 'exhibere' — 'ex' (out) plus 'habere' (to hold) — meaning literally 'to hold out' or 'to present.' The word walked into English in the 1300s-1400s via French, first for the act of presenting something formally (even legal documents could be 'exhibited'), before narrowing toward the gallery-and-trade-show sense we use now.
