Self-Appointed Saint Syndrome

(Abbreviated SASS) A state of mind in which the sufferer (the Self-Appointed Saint) patronizes others, under the belief that they helped those people attain some sort of salvation. Although it's similar to God Complex, SASS is different in that sufferers use an unnecessary amount of compliments and gifts to patronize their victims. This makes the victim feel as they are below the Self-Appointed Saint, and thus makes the Self-Appointed Saint feel like they are of an elevated status compared to others.

Person 2: Sounds like he's suffering from Self-Appointed Saint Syndrome
