The word ‘bossy’ can apply to either male or female. On the other hand the word ‘bitch’ applies to female unless you are transgender.
The corresponding guy terms are "bastard" and "asshole".
What the feminists don't get, is that the word "bossy" is applied to people who demand things be done their way, but who have not earned the right to issue orders through achieving legitimate authority.
A manager who demands things be done in a precise way, within her assigned scope of authority, is "firm". A low-level clerk who tells people to do things, without legitimate authority, is "bossy".
