A person who is very bad at something, does not understand something, or is a complete moron. Used in a friendly manner. Usually said forcefully. Similar to calling someone a fuck boy.

A drug stack (or simply "stack") is taking several drugs at once. It can have potential health risks, so they should only be attempted by professionals.
1.) My grandpappy used to take a drug stack of L-dopa, blood pressure medicine, and diabetes stabilizers, and wash them down with prune juice.
2.) Candy stacking is a drug stack consisting of ecstasy and acid.

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!

Faceplanted, fell, biffed, beefed, eaten shit. A person who has stacked has fully, bodily fallen all the way down, completely off of their feet. Always involves pain, usually accompanied by injury whether great or small, to stack is to hit the ground with your body, and without intention, so it necessarily hurts. A faceplant is always a stack, not every stack is a faceplant, thankfully.
This was common usage in skate culture in Northern California Bay Area in the 1980s, still used frequently by surviving GenX of that area, we have passed it on to our children. Probably came about by watching our friends fly off of their skateboards perpendicular to the ground so when they hit, it stacked their body onto the asphalt or concrete. I can't believe this isn't already here.

Chris hella stacked grinding that rail, he broke his clavicle and his nuts at the same time, he'll be in the hospital a few more days, but we can visit.
**"grinding a rail" refers to a skateboard maneuver that involves sliding your board down a railing on the deck- the part that is stood on to ride
