I've been reading a book where I came across the following sentence "I see you're working your shitkicker routine overtime. Sorry but we've got to talk." Does it mean here very boring,unsophisticated routine?
There are a couple of definitions for this vulgar word. It is sometimes used to describe a boorish person or sometimes an unsophisticated, country person. It is also used to describe an aficionado of country music. In the context provided, it probably means that the 'routine' being practiced is country music.
Some sort of country music dance would be my guess. (The implication is that your boots are all covered from the day's work and when you dance energetically you kick the stuff off of them.)
It's from a science fiction book by Larry Niven and Steven Barnes "THe California Voodoo Game". There's no sigh of it beind related to country music.
Then it likely means that he has been "stirring up trouble" or "kicking up s#$@" for other people in the office. The very opposite of being boring.
Now that I've read though this thread, I am reminded that the word is often used in reference to boots. Still the passage is not very clear to me.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
