poolista
Poolista is a term used in several online and vernacular contexts to describe a person who participates in a pool. Because “pool” can denote a monetary pool (such as a betting pool or prize pool) or a pool of participants in a contest, the exact meaning of poolista varies by region and platform. In many online communities that organize prediction pools for sports or events, poolistas are the entrants who contribute entries or stakes and share in any winnings or allocations. In other contexts, some languages use poolista as a colloquial demonym for players who regularly participate in pool games or billiards, though this usage is nonstandard and not universal.
The term appears to be formed from the word pool plus the suffix -ista, a common agent
Usage and connotations: In practice, poolistas are typically described neutrally as participants rather than organizers, though
