Why do we speak with modern slang in such a vulgar way?

Why are English cuss words so sexual/private? "Get your **** together." Was a slave from like 1400 forced to like... do something with their poo? 'f' this F that. "f... my life." idk how you can intercourse your own life. Why do we still use these words in such strange ways about things???

Classy people don't use that kind of language.

Language is constantly evolving. The British vulgarism 'take the piss' out of someone does not mean to literally insert a catheter and withdraw urine. That's been around since the 1930s, at least.

Slang is different from vulgarities. The dictionary says: "Slang is a type of language that consists of words and phrases that are regarded as very informal, are more common in speech than writing, and are typically restricted to a particular context or group of people."
Cuss words are in another bag altogether.
