To pull a Simskai

To let the fame rise to your head resulting in you becoming an arrogant prick who thinks he can become a Soundcloud Rapper, in the process losing all your friends and having to get on your knees begging them to add you back up on Facebook.

"Trump really pulled a Simskai there."
"Yeah, he fired all his staff and thinks he can become the next Post Malone."
