In the spirit of a Dirty Sanchez, a Dirty Dink is when you take your finger or your dick out of a girls ass and wipe it in her eye(s) which causes her to squint like an Asian.
"Wow. That girl is giving me the evil eye like Bruce Lee. She must have just recieved a Dirty Dink".
"I ain't gonna let my bitch drive for a while. She just got a Dirty Dink in both eyes".
