Duck face came to mind yesterday - randomly realized I hadn’t seen duckface in the wild for a long time.
Or, alternatively, what are some old fads you wish would make a comeback?
The spirit of the question is social fads. Please try to keep replies to lighthearted things. I’ll delete the post if the comments turn into political commentary.
Just publicly saying they’re in the know, and closer to the poster than anyone who doesn’t know. “Look at me! I’m such a close friend that I know who they’re talking about!”
