I'm always weirded out when Lebanese people who I hardly know call me Habibi. I mean it's ok when your grandmother calls you Habibi, but when the clerk at the store you bought chocolate from thanks you using this loving appellation it can get kind of awkward.
Take for example this sweet old lady sitting in her dimly lit shop, You pay her for your purchase and she replies "merci habibi"
Or some guy on a mobilette on the intersection "Yalla Habibi!"
Or the guy who jacked your car and your meeting in bekaa "Habibna!" (plural?)
Or the bank teller telling you its your turn "tfaddal Habibi"
A caveat of the Habibi rule is that it is NOT OK to kiss an attractive woman just because she calls you her lover. Good thing sexual harassment laws haven't come far in this country.
