What is the definition of Exmouth?

Exmouth is like the beach where the sun always seems to forget you exist, except maybe when you're trying to escape it with your sandcastle. Picture this: "As I ducked down Exmouth's infamous boardwalk to escape the midday heat, I thought I was finally out of sight, but then I realized I was right on the edge of the most dangerous part of Exmouth's geography - the cliff where the tide comes in and you can't even tell if it's a wave or a sentinel of the ocean's wrath."
