Nello Balan, the Ophidian-necked restaurateur, loaned a $1,000 "leather, limited-edition Jean Paul Gaultier" umbrella to a model friend of his named Le Call. Le Call, a model who has made a habit of receiving goods from kinda pathetic figures in the restaurant industry, refused to give the umbrella back. This made Nello very mad so he drafted a note to Le Call which "somehow" appeared in Page Six today.
I offered it to you because it was raining because I am a gentleman and I thought you are a lady. You called yourself an asshole! ....it may be true.... Stop behaving like a boulevardier [street person] and a petite voleuse [petty thief]. You don't give me the umbrella, I sue you.
According to dictionary.com, boulevardier is "a sophisticated, worldly, and socially active man; a man who frequents fashionable places; a man-about-town," so that's a weird thing to tell someone to stop being! (Babelfish renders it in English as "boulevardier.")
