Other forms: streamers
A streamer is a long narrow strip of coloured paper thrown or hung. Paper streamers, hang the streamers, throw streamers.
The name comes from the way it streams behind in the air. A streamer is also a long banner and, on a website, somebody who broadcasts live — a sense that has grown enormously and has almost nothing to do with the paper.
