http://en.wikipedia.org/wiki/Eric_Cartman#Personality_and_traitsCartman is an overweight, spoiled, lazy, foul-mouthed, mean-spirited, racist, sexist, anti-semitic, sociopathic, narcissistic, and ill-tempered third- then fourth-grader living with his mother in the fictional town of South Park, Colorado, where he routinely has extraordinary experiences not typical of conventional small-town life.
According to Parker, Cartman does not possess the "underlying sweetness" of the show's other child characters.[36] Cartman is amused by bodily functions and toilet humor,[37] and his favorite television personalities are Terrance and Phillip, a Canadian duo whose comedy routines on their show-within-the-show revolve substantially around fart jokes.
Cartman is in denial about his obesity, often reasserting Liane's notion by exclaiming "I'm not fat, I'm big-boned!"
In an action King's College philosophy professor David Kyle Johnson describes as "directed either toward accomplishing his own happiness or the unhappiness of others", Cartman often feigns actual friendship with his fellow classmates when needing a favor.[11] The lack of a true father figure in his life, and Liane's promiscuity and drug use have caused repressed psychological hardship in Cartman's life.[38] As a parent, Liane spoils Cartman,[39][40] and is largely ineffectual as a disciplinarian.[41] Cartman sometimes commands his mom to do tasks for him, but more often resorts to pleading with her in an ingratiating tone. When neither method works, he resorts to excessive and indecipherable whining, with Liane usually succumbing.
Cartman thrives on achieving ascendancy over others,[43] and exerts his will by demagogy and by demanding that others "Respect my authoritah!",[5] accentuating the last syllable of "authority" and pronouncing it /ɔːˈθɒrɨteɪ/.[41] He has shown initiative in taking a businesslike approach to earning money, starting his own "hippie control" and "parental revenge" operations.[44]
Carlos Delgado of If Magazine noted this as "Cartman being so egotistical that he manipulates the past to serve his own purposes"
