Mona Lisa Vito is the mean, vindictive girlfriend of Vinny Gambini in the 1992 movie My Cousin Vinny.
She was played by Marisa Tomei.
She is just so mean throughout the movie. She's arguative. She loves to argue for the silliest things, often being annoying to Vinny (how does Vinny find anything dateworthy about this girl? I'm sighing). She argues over stupid nonsense, when Vinny just tries to be nice to her. The biggest villainary is in a veiled threat (though it's comical) when she's on the stand testifying.
