Meaning:

“小学” means “primary school,” and “鸡” means “chick.” Originally from Cantonese, this term refers to “childish middle school students or even childish adults.” Sometimes used in its pinyin initials as “xxj,” this often appears in the discussion of fans who think someone acts immaturely. After popular candidate Justin Huang used the term on himself on the show “Idol Producer,” the term has taken on a new meaning of “being a cute rookie.”
