I invented you - You yell it when your friend gets all the likes and then act

You yell it when your friend gets all the likes and then acts like you're the background noise.

You: 'I invented you.' / Them: 'You're just the sidekick.' / You: 'I'm the main character.'

You message them: 'I invented you.' / They say: 'You're just the extra.'

In a video call, you shout: 'I invented you!' / They say, 'You're just the backup plan.'
