How would you define it in English? I'd guess (German is my first language, so words existing in both are always tricky) a) it's considered a lot more vulgar in English and b) is more general for a bad situation with s* flying around?

Correct on both points. Shit is a fairly strong expletive in English, so it’s not a word you’d generally roll out in polite conversation. And a shitstorm in English doesn’t have a specific context of something that happens online, it’s just any situation where a bunch of really bad stuff is happening all at once.
