Bad Manners and Brimstone

We may need more details like how or if the coworker affects you or your work. I'm afraid your description is too vague to determine if they are just annoying or actually causing serious harm.

But basically, you should avoid them and concentrate on your own work. Act distant yet professional if you need to interact with them. Document if they are damaging or sabotaging part of your work. That includes not doing their part of the project which can delay your own work. It's a good idea to document your own work too so they can't take credit.
