What is a plargarumpchi?
Anyone who sincerely identifies as a plargarumpchi.
Meaningless.
If a small child or an alien from outer space asked you what a woman was, would this answer help them understand? No.
If it makes sense to anyone, it's because they already know what a woman actually is. Which we all do, every one of us. Because long ago, someone else explained it to us properly. Adult human female.
Thank you Ricky Gervais!
