!+!-!!+!-!!!!+!!-!!+!-!+!-!+!!-!+!!-!!!+!!-!+!!-!!!+!!-!+!!!!-!!+!-!+!!-!!!!+!-!!!!!!+!-!+!-!+!!!-!+!!-!+!!!!-!+!!!-!!+!-!!+!!-!+!!-!!!+!!-!!+!-!!+!-!!!!+!

Explanation:

Each ! outputs a single bit. That bit is 0 if the current stack is empty, and 1 otherwise. Initially the stack is empty. + adds something (an empty stack) to it, and - removes it. As soon as 8 bits are output, the corresponding byte is sent to stdout. Therefore the sequence up to the 8th !, !+!-!!+!-!!! outputs the bit sequence 01001000, which is the ASCII code for the letter H.

The last character uses the fact that if at the end of the program less than 8 bits are output, the value is left-padded with zeros, and the resulting byte is output. So with comments (and spaces to make the output commands line up), the program reads like this:

 !+!-! !+!-! ! !  Output 01001000, i.e. H
 !+! !-! !+!-!+!  Output 01100101, i.e. e
-!+! !-!+! !-! !  Output 01101100, i.e. l
 !+! !-!+! !-! !  Output 01101100, i.e. l
 !+! !-!+! ! ! !  Output 01101111, i.e. o
-! !+!-!+! !-! !  Output 00101101, i.e. comma
 ! !+!-! ! ! ! !  Output 00100000, i.e. space
 !+!-!+!-!+! ! !  Output 01010111, i.e. W
-!+! !-!+! ! ! !  Output 01101111, i.e. o
-!+! ! !-! !+!-!  Output 01110010, i.e. r
 !+! !-!+! !-! !  Output 01101100, i.e. l
 !+! !-! !+!-! !  Output 01100100, i.e. d
    +!-! ! ! !+!  Output 00100001, i.e. exclamation mark

This pushes the string "Hello, World!" to the stack and automatically prints it.

Also, this is the first answer on the site! Woo!

Spent a good amount of time golfing this. I'm sure there's a few optimizations I've missed, but I don't understand the word "big" anymore.

Absolutely the shortest possible, no doubt about it. Try it online!. It won't work in the online one, copy it from there and paste it in the developer console if you are on chrome (as it uses the alert function). Please excuse my absolutely awful ascii art.

I also now see that this output isn't accepted (needs the comma and exclamation mark)... lol now it's time to figure out how I did this months ago so I can fix it ...
