Michael Dow, a linguist at the Université de Montréal, wrote an article analyzing different uses of the suffix, such as the merging of "Margaret Thatcher" with "-ussy" to create the portmanteau Thatchussy.
Why, I have a PhD in linguistics and several years of research in the field, yes. You might know my groundbreaking work, my opus major, about the thatchussy.
Depends, if they were a sex jokes I ignored them (See this page on why).
If they were trans/egg jokes about pussy they probably flew over my head because I do not relate to Women's experiences (really actually gender as a whole, see this page for more info on that).
So it might be accurate to say that I may have been exposed to it at some point here but it never stuck with me and I don't remember it, either because I didn't get it or because I ignored it due to it being a gross/uncomfortable discussion.
