eg: The stuff in that store is very pricey(贵的).
That's the stuff! 就是这个！
If you?stuff?something somewhere, you push it there quickly and roughly.
I stuffed my hands in my pockets...
If you?stuff?a container or space?with?something, you fill it with something or with a quantity of things until it is full.
If you?stuff yourself, you eat a lot of food.
I could stuff myself with ten chocolate bars and half an hour later eat a big meal.
But you're just so stuffed you won't be able to drink anything.
If you?stuff?a bird such as a chicken or a vegetable such as a pepper, you put a mixture of food inside it before cooking it.

Stuff?is used in front of nouns to emphasize that you do not care about something, or do not want it.
Ultimately my attitude was: stuff them...
1. ?Do one's stuff?露一手;施展自己的本事:If you?do?your?stuff, you perform an activity in the way that people expect.
eg: Once I get on the pitch I know I can do my stuff...
2. Know one's stuff?很内行;精通;懂行:If you say that someone?knows?their?stuff, you mean that they are good at doing something because they know a lot about it.
eg: These chaps know their stuff after seven years of war.
