unladylike

see unfeminine for an explanation of the subjective cultural meanings attached to this word. For the vague and often inappropriate "unladylike," substitute insensitive, indelicate, awkward, uncharming, unkind, rude, undignified, ill-mannered, ungracious, impolite, abrupt, etc. These adjectives apply equally well to a man and are not synonyms for unladylike but rather reflections of what society tends to understand by the word.
