I need a few words that describe a person who is imposing, in a context of overstaying his welcome. Someone that is present unwelcomed and you can't do your usual routines until the person is gone. A person who is not part of the household and is in the way. And excess person → freeloader, parasite, scrounger/unwelcome guest. Something more specific.
