FWIW, in my neck of the woods and in my childhood, “dork” was a synonym for “jerk.” My siblings and I often called each other dorks, and my parents never objected, except in the mildest “don’t call you sister names” sort of way. I didn’t know it could be a synonym for “dick” until today.
Isn’t it sort of dated now, anyway? To me, it’s kind of an '80s sort of word. I don’t think I’ve even heard it lately.
