YouTube lyricing

When someone knows all the words of a song and if anyone sings it wrong will automatically correct them, in order to present themselves as being cool.

Pablo: 'when your metro don't trust I'm gonna shoot him'
James: 'Pablo it's actually "if young metro don't trust you I'm gonna shoot him" but ya know'
Pablo:' James shut the fuck up, just cos your white ass was up all night YouTube lyricing the words, smh
