I understood your definition (all in all I had calculus 101) but to me it only describes why that is, it doesn't explain it. Most Big-O explainers don't assume a mathematical background because to non-mathematicians parsing your definition feels like being told you're in a hot air balloon. They see the what, but they don't understand the why.
