A foolish, incompetent, or insignificant person; also used in technical contexts to mean a unit of luminance.
Linguistics
Semantic Notes
The primary biological meaning is concrete and specific. The informal pejorative meaning ('foolish person') is derived via metaphorical extension, equating insignificance with a small parasitic egg. The technical term in photometry is unrelated and rare.
