Paraphernalia, artwork, or mind altering substances that trigger hallucinations or intensive introspective thought (as in tripping on LSD).
1. Dude, I told you guys earlier that I have to work late tonight, and to wait for me! Fuck, you guys already take the shtuff?
2. I mean this is an intense trip. Just earlier I was noticing trails and the walls were breathing... but now? I am feeling all types of shtuffs!
You gotta learn to roll with shtuff happeningin your life (e.g., a breakup, an accident, your dog dying), as it's schtuff that builds character and makes you stronger.
