"Move your ass" was evidently an acceptable way for a New Yorker to ask
somebody to make room on a bench or sofa, but would be rude in

strike New Yorkers as quite out of order.

Well, you have the advantage over me there. But as an Englishman, it
was caution about possible cross-cultural differences (on a predominantly
American forum) which caused my reticence.
