macho/machismo

by definition, only men are macho (the word is Spanish, meaning "male") or are associated with machismo; there is no parallel for women ("macha" is incorrect, although in Sue Grafton's "N" Is for Noose, one woman tells another, "Don't be macha"). You can approximate macho with sex-neutral alternatives: overly aggressive, defensive, proud, swaggering, overbearing, show-off.
