Trickstab

A word commonly used in the Team Fortress 2 community meaning a skill/action in which the player, playing as the Spy, uses certain types of movements to trick an enemy into doing actions that leads them to vulnerable positions, which the player can take advantage of by backstabbing them.

Vulnerable positions means positions where the enemy player's back (which is where the spy can backstab them) is exposed to the spy, often leading to the spy backstabbing them.

This can be done by tricking the enemy into making them turn to a certain direction or lead them to a position that makes their backs exposed.
