Bird scooters showed up in my city unexpectedly, literally overnight. We woke up and they were everywhere, like... a swarm of... Birds I guess. Suddenly everyone is zipping everywhere on these things and everyone says how awesome everything is. But then mad people go to Facebook and say that someone once saw a Bird scooter in a crosswalk and the city loses it's mind. They get lawyers to write letters to Bird (to demand... what? We don't know). They hear nothing back. Soon city council is complaining on Facebook too. The police impound them by the dozens, creating a phalanx of Birds in their lot. For a couple of weeks after that you are lucky to see one on the sidewalk. People are sad, but then, unexpectedly, Lime scooters appear, literally overnight, everywhere. Somehow the Birds are now free of their cage and everyone is zipping about town on scooters again. I think they are cool.
*flock of Birds
I must admit I had a little chuckle. I suppose there is a term for it when the correct answer is right there on the tip of your tounge but you just can't quite put pen to paper.
