A character with this trait uses one of the masculine Japanese pronouns, "ore-sama". Ore-sama comes from the Japanese masculine pronoun for “I; me (俺 or オレ)” and the very respectful honorific suffix, “-sama (様)”.
Since this is the most arrogant masculine reference of oneself, characters who use "ore-sama" tend to be aggressively overconfident and pompous males. Characters who utilise "ore-sama" are also known to be boastful, forward, hasty and having a “my way or the highway” attitude.
"Ore-sama" is also sometimes used as a personality trait term to describe such characters.
