The phrase comes from Spanish speaking players of Garena Free Fire, the mobile battle royale released in 2017 where gloo walls can be placed instantly to block enemy fire. In matches, calling for paredes gloo became a common desperate request when a squad is exposed. Clips of that call were shared on TikTok, YouTube Shorts and soundboards as a relatable gaming moment, turning a normal team request into a meme for any stressful situation where someone needs protection right away.
