New Yorkers I guess say "on line" instead of "in line" - I thought this was some kind of apoclyptic digital-age thing, but apparently they have always said "on line" here. It's also common to say "on" the Lower East Side instead of "in," like in the Blondie song In the Flesh where she sings
I saw you walking one day on the Lower East Side
which is really funny because it's a parody of 50's romance songs and the Lower East Side was trashy as hell back then. Anyway, "on the Lower East Side" doesn't really roll off my tongue, and I'm not going to say "on line," you know???
