What Does " Plant your arse" mean? for example in greeting? And Is it Rude and offensive? or is politely? or if its meaning changes in different situations please explain. And please provide me some synonyms.
It is used in informal speech in the UK, but not in polite speech. Said harshly, it could be a command to be still. Said as you walk into your local pub, a friendly invitation to share a drink.
"arse" being an inflected corruption of "ass," and in "butt." To "plant your arse" means to literally sit down.
Plant your ass, and assplat: slang and impolite:
The origin came from skateboardings all accidents when you fell on the ass, and the word assplant came up naturally. Then it became a thing to jump around and "plant the ass" on different kinds of thing.
- For example plant you ass on the roof of a car by jumping up and sit on it. Or if you accidentally fell, you can say you made a assplant.
I'd argue that the English is actually "park your arse", a slightly rougher version of the less offensive "park your bum" (all my students understand this!) I can't say for sure what the AmE version is, but I'd guess it involves changing the BrE "arse" or "bum" to AmE "ass" or "butt".
Also, there's the AmE "park your booty", but this has sexual connotations.
