If you haven't guessed:
It's just the word shit typed with so called leetspeak which makes it look unfamiliar.

5 --> s
h --> h
1 --> i
+ --> t

5h1+ --> shit

Used when you don't want to use offensive language, but need to name something "precisely".

Great for naming folders or drawers with random content inside.
- Hey, check out this: (some link)
- WHAT IS THIS 5H1+??

- Hey, check out my new track! (some link)
- That's some serious 5h1+, man!

- Some time ago I had a problem with my desktop getting full of stuff. Now I just made a little "5h1+" folder and threw everything in there, my desktop is clean and my stuff is safe!
