dirty ending

When you watch a movie and it ends without any specific conclusion, so the viewer feels betrayed; as if they had been shitting and there's still some left so their butthole still feels dirty.

1. "I just watched the end of the Matrix Reloaded and it was such a dirty ending."

2. "I just took a dump and I feel like I've had a dirty ending, so I should probably get back to dumping soon."
