Come up with eight words and/or phrases that have something in common. The next poster guesses what they have in common, and posts eight other words and/or phrases that have something in common. I’ll start:
Asian Flu, clip art, leaf blower, rumble strip, static cling, transsexual, clip art, Magic Mushroom.
Isn’t that 7 words/phrases? (“clip art” is in there twice.)
Sorry about that-the second “clip art” was supposed to be (appropriately enough) “overkill”.
Well, they have all the vowels except “y”, but I’m not thinking that’s it.
Try again. Their commonality is of a different coin.
They’re all compound words/phrases?
They all arose in the 1950s? It has to be something like that. Or they all were coined by the same news source or type.
When, approximately?
1957?
Exactly, according to Merriam-Webster.
Who’s next?
I will do one, but not right now, give me a few days, I have a meeting to prepare for.
In the meantime, someone else have at it.
Dumpster
Escalator
Kerosene
Ping pong
Plexiglass
Pogo stick
Zipper
They are all brand names or trademarks used as common nouns?
i.e. Tannoy, band-aid etc.
how about
Majestic
frugal
critical
baseless
obscene
castigate
countless
apostrophe
Yep.
mmm
Words derived from Shakespeare?
indeed, more specifically they are words commonly attributed to Shakespeare, that he coined or brought into common use.
(it is very debateable to what extent that is true)
That was actually going to be my next list. 
mmm
OK, here’s mine, an easy one to start:
Brain, Soul, Cat, Slow
