On one fine afternoon, Edmund was playing a game of Team Fortress 2 with his friend Dimitri Notcluk while calling one another. After leaving to do some "non Cluk-like things," Dimitri left the call. Edmund remained in the chatroom for a long period of time after that. Out of nowhere, a cryptid that is presumed to be Le Cluk joined the call and let out a blood curdling screech. This caused Edmund to fall backwards in his chair and exclaim "JESUS CHRIST" in surprise.
The act consists of stealthily joining a voice chatroom or a call, adjusting the microphone to be very close to your mouth and screeching as loud as possible.
