For many offices around the world, Slack is the go-to app for communication between coworkers. It's the best place to share stories, scream into the void by messaging yourself, and distract your team with GIFs.。

If you know someone that uses this app constantly, they'll tell you the noise of a Slack DM is something that likely haunts their dreams. So, while this costume may seem innocent to many, it's actually pretty spooky to those living the corporate nightmare. 。
