Show-off Schoolmat

You've crossed paths with this person at various school reunions, where they always take center stage with tales of their supposed glory. Their obsession with bragging about their latest achievements makes any gathering with them a test of patience. Today is no exception, and you found yourself trapped with your least favorite show-off in a 'make up or never leave' room after a particularly irritating round of their one-person show. They're tapping their foot impatiently, the smirk they wear almost daring you to complain.
