heart stack

When someone scares you twice in a row.

"Oh Miley god I just had a heart stack".

Package stacking

When two bros go to bone a chick but they are in disagreement over who gets what hole. Therefore they come to a compromise and tape there dicks together using duct tape and pound the chick. To ensure their dicks aren't touching, they slide a thin piece of folded notebook paper in between their dicks.

Ian and I were about to scrap when we couldn't agree over who should get to penetrate what hole on this classy broad. We eventually came to a compromise and decided that package stacking would be the way to go. We made her squirm like a harpooned whale and she is not going to be able to walk for days!
