A Phyllis is an ugly woman who is in kahoots with the devil. There is nothing good about a Phyllis or anyone that associates with one. A Phyllis spends her days doing mediocre art, eating Tuna Salad sandwiches, and plotting ways to destroy others with her Henchie minions. A Phyllis usually has a thick neck, chicklet teeth, and flabby skin.
That Phyllis needs to go to the mental institution.
