When a woman decides to take part in the act of masturbation. The "link" is the finger of the female and the "pink" is the vagina. The finger and the vagina link together/go inside each other. Thus creating a "Pink Link."
"Hey Amanda I'm going to do the pinklink"
"Okay Brittney just wash your hands afterwards."
All men wanna eat it then smash it all at once. Some boys wanna get at least more than one different cookie. I don't know why but I guess they like the taste.
