Kuva entered gaming vocabulary through Warframe, where it is a crimson substance tied to the Grineer queens and used heavily in late game crafting and Riven rerolling. Farming it became a routine, sometimes gruelling part of play, which helped the word become shorthand among players for effort and luck. Short clips named after it spread through soundboards and video edits as an in joke, and this version is kept alive by creators who drop the reference into streams, highlights, and memes about grinding and rare rewards.
