If we really want to be pedantic, most goth things aren't "goth" technically. If they aren't from late 70s Manchester blah blah blah. But that's not a useful or often used definition. Typically when it's used it's with reference to a larger culture. Generally tied back to punk or horror. So horror Punk is absolutely goth Etc. π As are TBM.
I may be biased. Once had someone pull me aside at a birthday party asking what the "shirt" was about. Only to realize I had worn my TBM shirt that day. I was like, it's a band and that's totally not what I'm plotting. You'll find out about that later. Though for the future I need to find some The Birthday Party merch to wear instead. Or at least Nick Cave. A lot less questions that way.
