Pentakill, shortened to penta, is the term used in League of Legends and other MOBA games when one player defeats all five enemy champions in quick succession. Adding en ranked stresses that it happened in competitive ranked play, not a casual match, which raises the bragging rights. Spanish-speaking players share short calls like this on clips, streams and soundboards, turning a rare in-game feat into a reusable celebration sound for wins, carries and unlikely turnarounds in other games too.
