Chronoposeur

A person who habitually arrives and stays late to both formal and informal events but has a knack for leaving a good impression anyways. The word is derived from the Greek word "chronos" meaning time and the French word "poseur" meaning someone who puts on a show or acts in a certain way. A chronoposeur is often seen as endearing and charismatic, despite their tendency to disrupt schedules.

My favorite Professor was late again today, but he is a chronoposeur.
