look up any word, like rimming:
 
1.
When you have sex with a chick with no condom, until you shower, you are known to have stink dink
I slept with Rachel today, and I still had stink dink from Jackie last night

2.
The stink that gets stuck all over your dink after you poke some dirty broad.
Your roommate: "Man, what's that God-awful stench?"

You: "Sorry dude, I need to wash off this stinkdink. I banged that dirty broad from apartment 6C last night."

3.
What you get after a long night of manhole fucking.
"Jeff, next time wash your ass before we fuck, you gave me a stinkdink!"
