(derived from sister), also sissy baby, sissy boy, sissy man, sissy pants, etc., is a pejorative term for a boy or man who is not traditionally masculine, and shows possible signs of fragility. Generally, sissy implies a lack of courage, strength, athleticism, coordination, testosterone, male libido, and stoic calm, all of which have traditionally been associated with masculinity and considered important to the male role in Western society.
