Crunchy pearl necklace

I learned what a "pearl necklace" was in science class when I was about 14. When we were sitting in the lab a friend of mine said he wanted to give one to our teacher (she was hot). In order to explain what it was he drew me a diagram. Below is an interpretation of the diagram.

A "crunchy pearl necklace" is when you give the chick a pearl necklace then you crumple up shitty Israeli crisps called Tapuchips and rub them into the spooge.

And voila - a lovely 'crunchy pearl necklace"
