Maniac. Some writers have been called this from time to time.
Mac. A computer writers use when they don't like PC's.
Mad Magazine. Ahahahahahaha Really funny writers contribute to this. (No, that is NOT how I became mad.) Humph.
Magic wands. Writers use these in their fabulous stories.
Mailbox. Writers love these when they hold royalty checks, loving letters from fans, idolizing letters from their editors. They DON'T like them when they hold rejection letters. (Huh? The dents in mine? Oh, those are from hail damage. I did NOT beat it with a hammer.) *hides hammer behind back* *grins shyly*
