A person who plays billiards or pool, or someone skilled with a cue stick.
From 'cue' plus the suffix '-ist' (meaning one who practices or specializes in something). Emerged in the 19th century as billiards became formalized.
Professional cueists train for thousands of hours to develop muscle memory so precise that they can sink difficult shots consistently—some can curve the cue ball around other balls using 'English' (spin), which seems almost like magic.
