Town Portal Kill - derived from Diablo 2 gameplay. When a character lures a large group of enemies into a small area then opens up a town portal and safely heads to town. He then tells other player that
the portal he just opened is safe & clear. The unknowing player jumps into
the portal and get swarmed by enemies then dies.
TPKs are used regularly on
Hardcore mode to kill off low level players quickly.
John: "My lv27 Hardcore warrior just got TPK'd by some asshole Hydra Sorc."
Me: "Daam, how'd that happen?"
John: "He said he was giving free Baal kills, so I jumped into
the portal, and
when the zone loaded up I was dead! He lured the entire fucking zone to
the portal"
Me: "HAHA! That'll teach you to play pick-up games!"
