When young people talk about stuff, they often mean something like the things that surround them or are part of their lives. It can be something material, like clothes or gadgets, or something less tangible, like music or lifestyle. Stuff is slang that has come to us from English, where staff and stuff can have different meanings, but in youth culture, they are often used interchangeably.
In youth slang, when you hear the word staffik, it refers to something important to a specific person or group. It can be anything, depending on the context, but always something that matters in their world. Sometimes it can refer to drugs, or to some small things. So here you need to be attentive to the context.
