Rule of thumb:

• are you making fun or otherwise mocking someone?
• are you doing it for any “bad reason” whatsoever?
• are you doing something that is/was primarily done by others for “bad reasons”, historically?
• are you doing something that other groups started doing as a replacement for something else that they were not allowed to (that you are)?

I’m half asleep so I may have forgotten something but if I didn’t, then answering No to all of those should be the minimum thing you do.
