A horse on you
A horse on you comes from a legendary joke where someone insults you so hard they bring a horse with them. It’s like being yelled at by a cowboy with a silver bullet.
A Horse on you! You’re the reason I had to eat the last taco.
A Horse on you! You’re the person who tried to sing and it sounded like a war broke out.
A Horse on you! You’re the reason the meeting got extended by 30 minutes.
