They can be used for either sex, they are old fashioned but I have used rascal and scoundrels particularly when describing the current administration.

Well, in my opinion it is kind of old, but at least we can still find some of the meanings in the dictionary.I think that all sex can use this but do not just blurt it out of your mouth.People will get angry at you.

You should do your own homework.

Besides, most of those words are never used anymore.
