I can only speak for myself, but it is a more intimate relationship than that of a work friend. "Intimate" doesn't mean "romantic." I spend much more time interacting with my work spouse than with any other co-worker. We trust each other with things we wouldn't necessarily take to other work friends, like plans for our careers. We also provide for each other: snacks, Tylenol, contact solution, a fresh pen, whatever.
