Holy crap; called that one.
To me, being "pretty poor" means that while you weren't starving or homeless, you regularly had to go without any real luxuries. You didn't go out to eat, or have soda in the fridge. If you owned a car, it was a cheap one. You couldn't afford special activities. What else would you think this means? If someone has some other definition, I'd love to hear it.
And that isn't "pretty poor", It's the low end of middle class but not "poor".
And the pants story is plumb idiotic.
ALSO: A lie.
