Killing all five enemy players in quick succession in League of Legends, announced by the game in a voice that has been imitated in every school in the world since 2009. The record's entry for the MOBA's highest score and its most-clipped moment, and the name of Riot's in-universe metal band.
I remember when Pentakill was still a niche thing — 2009 — and you could use it without a footnote. The footnote arrived about six weeks later and never left.
Filed as evidence: a job listing that asked candidates to demonstrate "Pentakill energy". Screenshot attached. The listing has since been edited.
The record notes the pentakill is usually finished by whoever arrived last, and that the four players who did the work call it 'KS' in chat while the fifth posts the clip.
What does it mean? Write it the way you would say it out loud.
