Naaaah. Nothing special or symbolic about such things. It's a short fad. I've seen hundreds of those come and go over the years.
What's annoying to me, is that a lot of fads are entirely artificially created and promoted, as I think this one was. Something that is mildly diverting, just odd enough to make someone chuckle that money was spent on it, is advertised as a latest thing, millions are sold, and then like a shallow tide, the fad passes, and we're back to our normal lives humming by again.
Remember hackeysack? Spinning hubcaps? Yo-yos? Those little balls of sticky rubber, shaped roughly like spiders, that we were supposed to throw against the wall, and then marvel as they slowly "crawled" down it? And all the fads in clothing? Hats that were supposed to get us laid, trousers that would let us watch an entire film and get fatter as we did, without pinching and causing us to leap out of our seats? Beds that crumple us into bent crones? Clap-on, clap off? I-phones? Sun glasses that make us able to see through reflected glare (maybe)? Wildly overpriced pillows that let us sleep better than ever before?
Oh man, don't get me started on old toys I had..
Hot wheel's by the bushel, corgi toys, wheelo, SST, Wizzer.. just to name a few.
