a very swaggy person

An asshole architect who thinks he/she is superior to all others on a project. Aristotects can be distinguished by their unusual, usually thick, black-rimmed glasses and their great effort to look out of place (i.e.: wearing 4" stilettos during a Construction site review)

Aristotects commonly drive Land Rover Discoveries, "for when they have to visit the site", despite the fact they they always park in a paved parking lot and are transported to the actual project site via a small golf cart or other vehicle.

My newest nickname for my enemy
