flitter

Flitter is an English verb describing rapid, light, fluttering movement; something can flit about or flitter about a room. For example, a butterfly may flitter from flower to flower.

The term derives from flit, with the agent suffix -er; in English it has long been used to convey capricious, quick motion. As a noun, flitter is less common but may refer to a person who flits from one thing to another or to a tool that produces a fluttering effect.

In nature, flittering is observed in small birds, insects, and other agile creatures that perform quick, darting movements. The word is often used descriptively in field guides and natural history writing to characterize rapid, irregular bursts of motion.

In modern technology and media, "Flitter" has been used as a product name for various software projects and online services. Most notably, Flitter referred to a Twitter analytics and follower-management service that offered features to identify non-followers and unfollowers, and to manage follows. Other uses include applications and products in different domains that adopt the same name.
