A male who has it all: class, is hot, comes off confident, and knows what he's doing. It is a combination if swag and chill. Usually this kind of guy wears Armani underwear and very fine clothing. A man/guy cannot be considered swill without such attire. Most girls seem to gravitate towards swill guys. Swill guys are the ultimate definition of hot.(especially guys in NYC)
Girl A: That guy I went clubbing with last Saturday is so f...ing swill!
Girl B: Really, you should get with him!
Girl A: I will!
