The action of solo-taking a "naked Nexus" in League of Legends game. This action is often confused with the more general term "backdooring" but the first one has more epic connotates. The verb "xpeke" clones the name of the first one who effectively xpeked: Fnatic Xpeke (from Fnatic team).
Your team takes both Nexus turrets but dies in the attempt of ending the game. You are the only one alive. All players in the game will spam:
"XPEKE IT!"
"XPEKE IT!"
