The infamous Matt Welch was in town last week and mentions having met “the raffish Julian Sanchez.”

raff·ish (adj: ‘ra-fish)
1 : marked by or suggestive of flashy vulgarity or crudeness
2 : marked by a careless unconventionality : rakish

I’m shooting for definition 2 here, though since most of our interaction involved a variety of bars, 1 might very well be the more applicable.
