Joe and Teresa Giudice move to South Park, Colorado where they became Stan Marsh's new neighbors. The Marshes invite the new family to dinner, where Teresa displays her bad temper and attitude, by gossiping about the people in South Park and insulting Sharon Marsh. Every time Teresa becomes angry, her husband Joe tries to calm her down.
Later, while at the beauty salon with her friends Jacqueline, Danielle and Caroline, Teresa becomes offended when asked to wait ten minutes for another client by the hair dresser. She became belligerent and nasty with the customers and staff until Sheila Broflovski, who was once also from New Jersey, slaps Teresa calling her a "psycho-bitch", as well as a trashy-whore. This made Teresa back down and leave the Salon in shock and horror, along with the other housewives.
Teresa has a dark complexion and wears heavy make-up. She is seen wearing a black and purple dress and gold bracelets. She has black hair with brown highlights.
Joe wears black pants, a black shirt, and gold chains. He has short black hair and is shown to be physically strong.
Teresa is abusive physically and verbally to everyone, while Joe is more conservative, as he tries to restrain Teresa. Teresa is also very ill-tempered and is shown as being prone to angry and violent outbursts at even the slightest provocation. They are both incredibly narcissistic and materialistic as well, with their primary concern being their physical appearances.
