Party on Aisle _: i'm not sure what to say about it
Definition: What the stacks is just like it sounds--it is a question to use when you don't understand what the stacks someone is saying, or they're doing something outlandish that's not worthy of a what the f___. This happens a lot when you're around people like Plumpie and Gas. On the internet, wts is more commonly used; don't confuse it with the other s-word.
