Lizzie and Sam are at the dive bar when the bitchy Mariposa sidles up beside them and intimidates Jason into buying her a drink. Afterwards, Lizzie and Sam overhear Mariposa on the phone and realize that Latin spitfire is just an assumed persona for Mildred, an ordinary girl who has learned how to channel her inner b**ch to get what she wants. The three women chat over coffee. Lizzie and Mariposa are both attracted to the same cute Waiter, and a challenge goes out – let the biggest b**ch win. Sam channels her inner b**ch with bike messenger Ryan and gets him to go home with her. They have wild, primal sex, but his interest fades in the morning when Sam inadvertently reverts to her nice girl self. Lizzie and Mariposa compete for the Waiter, but Lizzie can’t beat the master and Mariposa waltzes away with the prize. Later, a the dive bar, a Voluptuous Woman b**chily refuses to say where she bought her dress, so Lizzie cuts the label out of her garment. The dress is from a plus size shop - the Woman was embarrassed about shopping there. Lizzie feels guilty about her brazen behavior and apologizes. Sam goes home, and a deflated Lizzie stays at the dive bar. The Dirty Hot Guy sits down next to her, offers companionable silence, and buys her a drink.
