Gangplank is the pirate captain champion from League of Legends, a game released in 2009 where a pentakill means one player taking down all five opponents in quick succession. This Brazilian clip is tied to a pentakill credited to Zeref, and it circulates among LoL players who use short match clips as reaction sounds. Its appeal comes from that rare, match-defining achievement, so the audio has become shorthand in edits and chats for a perfect gank, a clean team wipe, or bragging after carrying a game.
