This Slack costume might just have won Halloween

Lots of workplaces use Slack as a form of communication.

So what better way to terrify absolutely everyone than to dress as a walking, talking reminder of the terrible, dark nine-to-five?

Twitter user Alex Novemberg did just that for Halloween.

Dressed in a t-shirt with the slack colours and a spine-shivering black ‘s’ planted in the middle, he even managed to nail the sound made when you get a new message.

It's so meta.

Needless to say, people were terrified.

#Shook.

Others were impressed by the simple genius of the costume.

Stomach-churning anxiety is the reaction you want to your Halloween costume ​tbh.

Even Slack was on it...

Novemberg FTW.
