So the original is split into parts with spaces. Each part uses a different combination. So maybe for the copypasta, create similar segments but maybe with slight variations.
Another approach: think of the letters as representing sounds, like UwU or OwO, but more frenzied. Maybe the copypasta is a keyboard smash but structured. Alternatively, it could be mimicking someone mashing keys in excitement or frustration.
So, to create a copypasta in that style, I need to generate sequences of U, W, G, H in alternating patterns, with some runs of repeated letters. Let me try composing each part:
First segment: Maybe start with U and W again, but perhaps a different pattern. Like "WUWWUWUUWUWU". Then a G segment: "GUGUGUGUGUHHGUGU". Then a part with H's: "GHHHHHHHHHHHHHHUUUU". Then a mix: "UGHGGGHUUUUU". Finally, end with WU pattern: "WUWUWUWUUW".
So the problem was entropy apparently.
