mozo
I once used "Mozo" in a mexican restaurant in St Louis to summon our waiter. All the waiters were mexican and everybody there knew me well enough, but they still all busted out laughing. Turns out the mexican flavor of the word used thusly was that I was admiring, and maybe even, flirting with him.
I don't think I could have turned a brighter shade of red.
Doncha love spanish?
