陪玩

陪玩 is a peer-to-peer gig: you pay someone (often a young woman, often via apps like 比心 or 捞月狗) to play 王者荣耀 / 英雄联盟 / 原神 with you, chat on voice, and possibly carry you. Pricing is per-hour, with premium for 大神 (high-rank players) and for friendly voice chemistry. Distinct from gold-farming - the service is the company, not the loot.

Generic sense ('to keep someone company while playing') is older and innocent - kids 陪玩 a younger sibling. The gig-economy meaning dominates online discussion since around 2017.
