look up any word, like spook:
Phrase I invented to describe money needed by chicks to buy stuff they don't need. For example, clothes (which they neither need or will ever wear) or random presents for other people.

Note, this money doesn't nescessarily have to actually be spent on tampons, its just money that girls think they need, and require a constant supply of, but actually they can very easily live without it.
-"Man I'm broke."
-"Already? I thought you cashed in your paycheck last week!?"
-"Yeh but I have a girlfriend, remember?"
-"Tampon Money. Sucks."
