From 'flaunt' + '-y' + '-est' (superlative suffix). The superlative form expressing the highest degree of being showy or exhibitionist.
Superlatives like 'flauntiest' are linguistically interesting because they force us to rank qualities—we're saying 'this is the most showy of all'—which is actually quite a subjective judgment in social situations!
