Self defecation is the act of being able to
make fun and/or light of yourself in an effort toward 'humanizing' yourself. Actually that is the definition of 'self deprecation' however
self defecation is self
deprecation BUT to the 'Nth' degree. To further explain, the antonym of being self deprecative would be 'pompous' while the antonym of being self defecative would be that of a 'complete pompous ass'.
