Somebody who is always walked all over

When you think up something brilliantly righteous while baked.

A person who allows people to treat them badly or walk all over them.

Someone who's really nice, kind, generous and sweet; often also smart and funny. They can be outgoing and extroverted, but still allow certain/most people to walk all over them.
They are dedicated friends and partners, and infallibly there for anyone who needs them with advice, support, money, homework to be copied, and expect nothing in return.
They desperately wish one day that someone will call them a friend and mean it, but for now they are happy to be a friend to everyone else no matter what the personal cost.

They actually LIKE to be used, because at least it means they are needed in some small way.
People might see being a doormat as a sad and pathetic existence, but doormats are generally content with their standing.

Someone who lets their so-called man walk all over them!

An object you place in front of your door. ffs
Not a person you treat as if they were a doormat. You know, walkin' all over 'em and makin em feelike shitlike WHAT?
You gonna do that?

A doormat is simply an object placed before an entryway into someone's home. It is NEVER a human being that is treated like some planar object you can just walk all over, wipe your shoes off on, and then enter into the person's home I can't even get into. I can't get in there, because - hint hint - I'm a fucking doormat. So sure, I'll stay out here, glad I could be of help.
