TKer

TKer is short for "teamkiller", a common computer gaming phrase used to describe players who attack members of their own team instead of members of the opposing team. In the context of Urban Dead, it has been used to describe both survivor players who kill other survivors (PKers) and zombie players who kill other zombies (ZKers).

The term is rarely used, with "PKer" and "ZKer" being more common.

A typical survivor caught in the act of Christmas Tree Killing.

Alternatively, TKer (or TrKer) can mean "Tree Killer" as in one who destroys christmas trees, which are temporarily introduced into the game by Kevan yearly during the Christmas season.

Tree Killing, similarly to TKing, can be punishable by some groups by death. However, it is commonly a rarely cared about occurrence.
