f'show - You're so sure you're gonna win that you're already planning

You're so sure you're gonna win that you're already planning your victory party.

F'show, I'm gonna win this game. I'm already texting my friends to come to my victory party.

F'show, I'm gonna beat you in this spelling bee. I'm already buying cake.

F'show, I'm gonna win this dance-off. I'm already telling my crush I'm gonna ask them to the prom.
