No longer fashionable or modern; out of date or old-fashioned.
From French 'passé,' past participle of 'passer' (to pass), literally meaning 'passed' or 'gone by.' Entered English in the 1700s to describe things that had passed their prime.
What's 'passé' changes constantly—bell bottoms were passé in 1990 but came back cool by 2020, which proves that fashion moves in cycles and 'dated' is really just code for 'waiting to become trendy again.'
