I have an idea of what a “Tumblr sexyman” is only because younger people brought up The Once-ler in a social media conversation about censorship. I’m… no less confused after passing the F.F.A.R.T.
I don’t know if I have any better answer than what my friend said, “a tumblr sexyman is a well dressed thin guy who may or may not be human but he’s also a little pathetic” - is the millennial equivalent a scene kid? 🤔
