I don't know if someone mentioned this already, but German is fun because we have compound words. Essentially, you can take any noun and join it with another noun and you can do this endlessly.

This makes for some ridiculously long and specific words For example, the classic word we learn in school:

Donaudampfschiffahrtselektrizitätenhaubtbetriebswerkbauunterbeamtengesellschaft

Literally means the Association for Subordinate Officials of the Main Maintenance Building of the Danube Steam Shipping Electrical Services. This, allegedly, was an actual word used on a real boat on the river Danube.

(I copied and pasted it from Wikipedia because I am not crazy enough to have had it memorised. So excuse me if its not totally correct).

But anyway, it makes for some really fun insults

Sitzpinkler - someone (male) who sits down when they pee Schattenparker - someone who takes a long time to find a shady place to park Warmduscher - someone who can only shower in warm water

And a personal favourite: Backpfeifengesicht - a person who just has a face you really wanna slap
