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.  。
