A common behavior in Christian cultures. Consists of insisting how Christlike you are. A "Christier than thou" way of acting. This is used by many Christians whether they are generally nice people or disgusting POS's. The traits that practitioner will claim to have are usually called love, charity, compassion, caring or forgiveness. Some practitioners merely declare their Charitas publicly. Others take you to task publicly for your lack of Charitas. This trait is a central feature of American culture.
"American exceptionalism" is a close relation to Pseudocharitas. Thus Obama can mow down Pakistani children because everybody knows how Christian he is.
