What's sign-language for boobs?

I was walking home from the T-Mobile Sidekick launch party tonight and stopped at a Don't Walk sign. Three guys walk up behind me and there's a bit of a kerfuffle. I turn around slightly and see one guy point at me, a bunch of rapid sign language transpire, and then one of the guys making the universal sign for boobs (uh, two hands cupped in front of his chest). Then there was some general jolliness and more signing.

I can't be sure, but it seems I may have just been sign-language harrassed.
