Yeah, there's a kind of selection/reporting bias online where extroverts and exhibitionists get the most exposure. It could well lead you to conclude that a significant proportion of women are morbidly obese, or green-haired harridans, or tattooed and pierced on every inch of skin. Luckily this isn't indicative of the quiet majority.
Tattoos on women have definitely become far more common in the last 15-20 years but I think they've now reached such a critical mass that they're undermining their own purpose. There's no longer anything shocking, unusual, rare, edgy, etc about having a tattoo: every fucker has one. Decades ago having a tattoo suggested you were a hard nut, merchant navy, ex-services, ex-prisoner, in a gang, or similar. The old bloke down the pub with an arm covered in ink; each of those represented a place or a person or an interesting story. The whole thing has become gentrified now. You can walk into your local parlour, point to some designs in a book, and emerge with a full sleeve that same afternoon. What's the point, beyond surface level aesthetics?
One of the most conceited trends I saw a few years back was deliberately scarring yourself across a cheek or down an eyebrow, to look tough or heroic. Again, completely missing the point of authenticity. If you have a cool scar, the first thing people will ask is "how did you get that" - you'd either have to straight-up lie, or admit that you paid to sit in a chair and have somebody wearing nitrile gloves cut you with a sterilised razor. Absolute vanity.
