Apparently, some people like having their nasal passages impaled for Covid tests. So much so that there is a slang for this penetration. It is called “nussy” and it rhymes with a similar word that starts with a “p.”
Urban Dictionary gives a different definition for this word but Twitter has claimed it and now there are videos on YouTube of people doing this in a sexual manner. As someone who has had this test, I find this perplexing. I found it about as far from a sexual experience as one could imagine.
