Cadillacin: "To chill around your crib all day long with no apparent plans or motivation to do anything" (Urban Dictionary).

Kyle is one of my roommates for this summer, and a gentleman and a scholar.  He drives a 20-year-old Cadillac Eldorado Biarritz with less than 60 thousand miles on it.  He bought it from his grandpa.  While I wouldn't want a 4.5L V8 under my hood, it's fun to have a roommate who does.  This car doesn't just have character; it is a character.
