The answer is sissy. This is a disapproving term for a boy or man who does not follow the "standard male" gender stereotypes. Commonly, this implies a lack of bravery, strength, and muscularity, all of which have customarily been associated with masculinity and considered significant to the male role in Western culture. Sissy is said to be the male converse of tomboy but carries more powerfully negative connotations. According to a research printed in 2015 suggests that the two are unequal in their power to brand: sissy is almost always pejorative and carries greater severity, while tomboy rarely causes as much concern but also produces pressure to conform to normative gender roles. Applied to an individual, these terms become a form of social control, implementing normative gender roles and often picturing on the unfounded link of gender nonconformity with homosexuality.
