z lister
someone far far from being a celebrity but somewhat known, if not by name then by face or reputation
"Everyone in Wollongong knows her, she's a z lister"

"I knew his name long before I knew him, it was like an itch in the back of my brain and I couldn't quite just put my finger on how I knew him, probably just some local z lister."

Taylor Swift -

'Your ex-friend's sister
Met someone at a club and he kissed her
Turns out, it was that guy you hooked up with ages ago
Some wannabe Z-lister
And all the outfits were terrible
2003, unbearable
"Did you see the photos?"
No, I didn't, but thanks, though'
