hit frog bottom
Used to describe moments where the vagina has acquired a less than desirable smell. Common instances would be while spending extended periods of time sitting at a desk with tight dress pants on. May also be known as "crotch rot".
"whats up girl..how was work?"
"I tell ya, I hit frog bottom sitting in this chair all day. I don't know what is going on with my junk!"
