I work a lot with people who are incarcerated or who live in poverty - the term "stay" is often used by those populations to indicate that they don't have a permanent residence. They may move from place to place very frequently, and thus have no real "home" or long-term permanent living situation.
I'm sure it originated with temporary situations or people in temporary situations, but I head people who own their homes say it.
I know it is a colloquialism.That's actually a colloquialism in parts of the AA community. I've seen some very heated discussion about that. Apparently it can be a sensitive topic. I was not familiar until I witnessed the discussion.
Many of the other posters mentioned colloquialisms or regional dialects that bother them. I just don't like that one.
