Turning Point USA is Charlie Kirk's far-right propaganda organization, theoretically aimed at college students, but actually aimed at senile boomers. They're making cringe ass far-right memes and funded primarily by infamous fossil fuel billionaire Charles Koch, and formerly by David Koch before he died and went to hell.
Random dude:"Hey! Have you ever heard of Turning Point USA?"
Every sane person:"You mean that far-right organisation that makes cringiest memes on the internet? Yeah, I've already heard of them".
A significant or life changing event.
First used by "TSN"(The SportsNetwork.) In every hockey broadcast on this station they include a feature named the TSN Turning Point; where they show the highlite that most influenced the outcome of the game.
That right hook you threw was definitly the TSN Turning Point in that fight man.
