shat your shot

A play on "Shoot your shot" when asking someone out, to "shat your shot" means you asked the person out, but you botched it with the result that you were rejected.

You "shat your shot" when you botch a proposal to ask someone on a date. For example, saying the wrong name.

:::Asking out Becky:::
"Hi! I was wondering if you wanted to go to the movies, Cindy."
You just shat your shot.
