The Act of creating two Blumpkin Pie's; then using said pies to create a sandwich for the woman to eat, while you prepare the coconut for the Coconut Surprise
Bro your sister is insane. I came home and found your brother performing The Double Blumpkin Pie Sandwich With A Coconut Surprise on her. I can't believe she just sat there and ate it! I was so excited when your dad walked in with the coconut.

A slight twist on the original blumpkin.
The double upper involves a male taking an upper decker while a female is taking a dump in the main bowl of the toilet while facing backwards. While all this is happening she is blowing him.

My buddy and his girl would have a few drinks after a night of eating hot wings. When they got home they were both so horny and had to shit so bad that it would inevitably turn into a double upper blumpkin.
