Writer's Bottom

... I do have writer's bottom.

Forget writer's block
I've got writer's bottom
It's not the same thing
It's much more rotten

There's nothing to be done
To save the writer's arse
At least if you're blocked
You can hope it will pass

So forget writer's block
Until you know what it's like
To have writer's bottom
Is to know how hard it is to write.
