    It means Siddown!; plain speaking, informal speech. Often used between old friends or colleagues, or to simulate friendship and collegiality in the appropriate context. Commented Aug 18, 2014 at 17:25

    Worth mentioning also that the degree of offence the expression might cause will vary from 0 to a very large number, depending on context, tone of voice, relationship between speaker and speakee, the usual factors. Commented Aug 18, 2014 at 17:32

    Isn't "arse" BrE, @FumbleFingers? I suspect that "Plant your ass" might be used in the US...where, I'm not sure. Commented Aug 18, 2014 at 18:04

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.

    In fact 'ass' is a corruption of 'arse' not the other way around. Ass means donkey but has come to mean 'buttocks' in US English. The word 'arse' goes all the way back to Old English ærs "tail, rump" etymonline.com/… Commented Oct 31, 2015 at 18:35
  • @chaslyfromUK It’s not so much that donkey came to mean butt, but rather that the r was lost. There has been a sporadic tendency to reduce root-final /rs/ to /s/ throughput the history of English; it’s never been a general thing, but it’s left its mark here and there; compare bass (the fish) from earlier bærs; cuss from curse; bust from burst; etc. Commented Nov 3, 2018 at 23:45

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.


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.

    It goes a long way further back than skateboards!
