I invented you
You say this when your friend gets famous just because they're with you and then acts like they're the king of the castle while you're stuck in the dirt.
You: 'I invented you.' / Them: 'No, I invented you.' / You: 'You didn't even exist until I showed you the light.'
You text them: 'I invented you.' / They reply: 'You're just jealous I got a million followers.'
In the middle of a concert, you yell: 'I invented you!' / They roll their eyes and say, 'Yeah, and I'm gonna take your throne.'
