This is the back part of the knee on
men or women. Also known as the "
Legendary Fourth Hole" in women. You can only see the dinkus from exactly the right angle much like the entrance to
Hogwarts.
Multiple: Dinkii, (dink-eye)
Dude, I've got massive dinkus sweat...
Man 1: What'd you do last
night?
Man 2: I did this
chick in the dinkus last night. Hands down
best sexual experience of my life.
