Do you know what a courtesy flush is?

I know this sounds weird but I have never heard of it. One of my cousins was being nasty telling us she had to do a courtesy flush so many times because she didn’t wanna stink up the bathroom and her private parts had a tingling feeling. She didn’t have to say it so bluntly but it was just us ladies. She said she had too and she wants to be clean.
