tattoo question
somebody mentioned this in an earlier post, and it's entirely possible that it's been discussed here before, but i don't really want to have to go through all the pages.
i've been wondering about the tattoo scene - where johnny kinda flips out at the older woman's tattoo (was it a skull? i can't really remember). the reaction is certainly important, but i'm not entirely sure why. the first and most obvious answer would be that it's some obscure marker for an STD/Disease/Etc, but this film isn't usually that literal... any thoughts? am i just way behind on underground english culture?
thanks.
