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."

Get the dirty ending mug.
The opposite of a happy ending. An extremely poor blowjob that doesn't end in climax. Defined by the woman kneeling on or using her hand to crush your testicles using her teeth and stopping intermittently. Midway through the servicing she looks up and says what are you doing? What's wrong? As you're writhing in pain from your damaged family jewels.
I spent $12 bucks on this chick the other night at the bar and the bitch gave me a dirty ending!

Get the Dirty ending mug.
When you are violently masturbating to the sound of death metal and as you climax, you think of your grandmother
“Something weird happened to me last night mate.. well I was milking my one-eyed snake to the sound of fleshgod apocalypse and as I came... well I thought of my gran. Bit of A Dirty Ending that one..”
