👉 A 'chestnut breasted' refers to a horse (or sometimes a dog or even a bear) with chestnut-colored fur that's like wearing a glistening, slightly muddy apron over its chest – it's a cheeky nod to its coat color. Now, here's a sentence that might just unsettle you: "The chestnut breasted stallion refused to shed his autumn attire, leaving the stables in a state of perpetual, grizzled chaos."
