An adjective to describe the way traditional business men (usually art world) look when dressed up for a meeting, dinner, conference, etc. This is in juxtaposition to younger guys who do similarly important business in a casual, informal way (in jeans, hoodie, hip, etc.)
"Those old guys at the table across from us are looking mad dealy. LOL" "Yeah, there must be a deal going down."
