You ever walk up something that seems easy but leaves you breathing hard? That's the real deal slope, not some gentle hill. corar37 gets it, folks throw the word around too much.
Honestly, corar37 has a point about people blowing things out of proportion. The difference between a slope and a hill isn't just about inches on a map. It's about how it actually feels to go up it. A real slope makes you lean into it and changes your stride. Calling every little bump a slope is how we end up with no good words left for when you actually face a long, steep climb. It just waters down the meaning.
