The stack is a sum of money or of other equally liquid financial assets.

The stack only goes up or down and it's your main job to make it go up.

The stack is your best friend.

The stack doesn't lie, doesn't cheat and doesn't betray. The stack doesn't judge you, doesn't harm you and doesn't plot against you.

The stack is always there for you, in good times and it bad times.

It makes bad times better and it makes good time amazing.

The stack might make some of your fake friends jealous and it's best enjoyed with your real niggas, the ones that were there for you when you didn't have much stack.

When lost, just look at the stack for mentoring: will the stack go up or down following your action? Once you know the answer, you know what to do.
Momo: bro, if I had to teach one and only one thing it would be this: keep your eyes on the stack. Don't let ego or hoes get in the way. The stack is the final answer of your every action.

Get the STACK mug.
When a group of 2 or more people sit on each other's laps over a toilet and piss together.

(Although it is usually practised with piss, the person on the bottom of the stack could theoretically poop, as well, though it would be rude for someone higher in the stack to do so)
"Hey guys, you ever tried stacking?"
"No, but I need to go to the toilet, wanna stack with me?"
