the.com/upstart

means A person who has risen suddenly in rank, wealth, or influence — especially one seen as pushy, presumptuous, or undeserving of the status they've grabbed.

from Straightforward 15th-century compound: 'up' plus 'start,' meaning to spring or shoot up suddenly, like a plant bolting out of the ground before its season. The word first described a sudden rise itself, then quickly curdled into an insult — the person who sprang up too fast, too far, without the pedigree or patience the old order thought they owed it.
