Yes, the younger generations have a fondness for shitty tattoos. One girl at my gym started her OF and made a small fortune as a so-called 'muscle mommy' - which I don't get either since she has no kids, anyway her niche was her tattoos which were all black symbiote - think the Alien from the movies- half her body is covered in black ink and it looks like shit.
Then there's all the girls who are mothers and have some chain/necklace/bracelet tattooed around their wrist with their kids names spelled out.
Or the random vegetation, whether it's all roses or flowers or vines of some kind...
Then there's just the completely random images: Pinocchio, Paddington bear, possums, skulls, shell casings, some celtic cross, a flag of some country denoting heritage, roman numerals.... it goes on and on.
In the effort to be an individual they look just like everyone else.
As for the complete black ink sleeve. I think its a symbol that you are a woke , radical, liberal. They're the only one stupid enough to get an entire sleeve of black ink.
