I'll bite on the "trap". I would not like to be called "manly", because I'm socialized to place an extremely high value on my feminine characteristics and traits. It's important that women "look" a certain way (attractive), act a certain way (accommodating, nice), etc.

Calling a woman "manly" is not an insult to men. It's an insult to a woman because you're telling her she's not acting or looking womanly enough.
