Most of it is gen z slang, but there's a bit of gen alpha slang as well

Geringverdiener (noun) - other word for loser

Schere (noun/exclamation) - means "my fault" or "I blame myself"

Alman (noun) - A person with stereotypical German behavior

Talahon (noun) - A person with a certain behavior. This behavior includes hanging around at train stations, wearing fake Gucci clothes and bum bags, trying to beef with random strangers, and shadow boxing. Sometimes this word is used offensively, but that doesn't always have to be the case.

N word but with d instead of n - means something like bro or dude

i was lwk just about to say "my [that word]" but i would probably end up banned even in this context

My [that word] is grammatically wrong, that word is used without words like "my" and "you"
It also has no plural

oh ok well now if i said it i would definately get banned

This one might be the most used slang word in Germany, and I can't even spell it out :(
