The clip comes from the US version of The Office, in the 2008 episode Frame Toby, where Michael Scott discovers that Toby Flenderson has returned from Costa Rica to HR. Michael's long standing hatred of Toby turns a normal office moment into pure panic, and fans clipped the scream as a reaction and GIF across forums and social media. It stayed popular because almost any unwanted return, sequel, update or person can be framed the same way, making the exaggerated horror instantly relatable.
