also, ear tags are the livestock thing, these tags are also given to some stray animals in some countries to indicate they have been neutered... those usually are in the right ear also
i remember there was all kinds of superstitions about piercings when i was young, "right ear means gay, left ear straight" and shit like this, and then by my mid teens there was all these rockstars getting septum and eyebrow and industrials and nipple piercings and shit
i'm kinda glad the fad has died down a bit, but there's a culture that loves this stuff, hipster, hippy, woke, when i got my stuff done it was much more grass roots underground than now... i even died my hair with a bright red spiral when i was 18 living in a share house behind an anarchist bookshop... haxing the internet in the early days with an old macintosh with terminal emulator... ah the stories
