It appears there may be a typo in your question. "Fesbian" is not a recognized term. Could you provide more context or clarify your question?
According to UrbanDictionary.com, a Fesbian is someone who pretends to be a lesbian to gain attention from guys, or because being a lesbian is the "cool thing to do."
