metaphysical dock

It is the same as the original ned's dock *cough cough* that is, a non existent penis

Girl 1- Omg! I found out Carl has a metaphysical dock yesterday!
Girl 2- That's awful!! What are you going to do?
Girl 1- I'm going to have to leave him, he can't please me.

Girl 2- What a shame, I kinda liked him.
