(Note: There are no swear words in this post.)
Are you surprised that you should learn German swear words? You shouldn’t be.
German, like every language, has its own group of salty words. And Germans, just like every other people, decide individually on if and when they swear and in which situation(s). And since they are overall a polite and diplomatic folk, it's not that often. Swear words are still considered naughty words.
A language is a living thing, and swear words and slang are a part of that. These are words which change over time (remember “rad” and “syche!” from the 90’s?!); a language is an expression of and is also part of its own culture.
When I say "learn German swear words," I mean know what they are. Recognize them. Know if something is bad or really bad. Know when something you hear is someone telling a joke and know when something is a direct insult.
Let’s take a look at why it’s important to at least know what swear words are in German:
1. You don’t want to misuse a naughty word.
This is one of the biggest "jokes" that people like to pull on German learners. German speaker Lukas teaches American speaker Will a naughty word, and either doesn't tell Will what it means or he tells him that it means something else. Will tries it out in conversation and offends his new friends.
