Shut up Intern 2! is a line on MyMusic (show). The line usually is used when Intern 2 points the obvious in a conversation, or when considered by others as cramping their style. The line is mainly used by Indie, who shows that he has a strong hatred towards him.
However, once in a while, others would also say it. They then are told to shut up by Indie, admonishing them, "Only I get to use that phrase to Intern 2!" This has happened to Idol in Season One.
In Trolling and Jolting, Intern 2 has a friend called Lab Tech 2, who was told to shut up by the Lab Tech Boss at the Acid Factory.
In the 18th episode of The Mosh, Intern 2 was told to shut up by a voicemail from a fan in the Call Me Maybe segment.
Since Hip Hop has revealed his nerdy side, Indie has been saying the same thing to Hip Hop: "Shut up, Hip Hop!". This was first seen in Season 2 Episode 2 (Nerdophobia?).
After Straight Edge's true colors were revealed, some fans have taken to using the phrase "Shut up, Straight Edge!" on his social media accounts.
The phrase was later reused for the final time in the 66th episode of The Mosh, because Intern 2 already changed his name to Flowchart.
In the 24th episode of the Podcast, which was removed due to a copyright claim as of June 2020, due to Intern 2's new nickname, Metal came up with the new phrase "Eat a fart, Flowchart!"
