How about calling them loud-mouthed and obnoxious if they are loud-mouthed and obnoxious. How about rounding them up (the ones vomiting on the streets and disturbing the peace) and making them clean up the streets the next day with toothbrushes. And having video cameras up here and there so they can be identified and made to do some sort of community service.

Sorry, mg. We are not allowed to do that I'm afraid :-( These poor little dears would be horrified to think they had to do some sort of work and their protectors on here would be aghast that you have suggested such an evil thing. They are only obnoxious and loud-mouthed becaue they are victims of society. Now please go and wash your mouth out...
