>>7367171>"Paper tiger" is a literal English translation of the Chinese phrase zhilaohu (simplified Chinese: 纸老虎; traditional Chinese: 紙老虎). The term refers to something or someone that claims or appears to be powerful or threatening, but is actually ineffectual and unable to withstand challenge. Seeing as she acts extremely haughty and smug but folds immediately when things don't go her way, becomes despondent and needs reassurance and positive affirmations to cheer up again.
But when she starts winning even a little bit after that, she starts being a smug ojou-sama again.
Happened half a dozen times in her Jump King stream alone and I love her being a little shit like this.
