the.com/jockey

A tiny adult whose job is convincing a half-ton animal to run somewhere pointless, fast.

means Someone who rides racehorses professionally, or more broadly, someone who manipulates or maneuvers something into position (as in 'to jockey for advantage').

from 'Jockey' started as 'Jock,' a Scots and Northern English pet form of 'John' or 'Jack' — basically the medieval equivalent of calling every third guy 'Buddy.' It became a generic term for a common fellow, then narrowed to mean a horse-trader or hired rider, since that's who you'd find hanging around stables. The verb sense, 'to jockey for position,' galloped out of racing slang in the 1700s, when riders would jostle, cut, and angle for the inside track — a move that apparently needed its own word because everyone recognized it.
