The phrase comes from Drake and Josh, the Nickelodeon sitcom about two very different stepbrothers living under one roof. In its Spanish-language version, 'oye, tranquilo viejo' became a quotable way to tell an older man to calm down, and the office setting in the clip's title helped it circulate as a workplace reaction. Shared through meme pages and soundboards, it survived because the line is short, instantly understandable and easy to drop into any moment when someone is taking a small problem far too seriously.
