From Nookipedia, the Animal Crossing wiki
Buck (ヴァヤシコフ, Vayashikov) is a jock horse villager in the Animal Crossing series. As a jock villager, he will appear friendly and competitive when around the player. His name may refer to a vaulting horse used in gymnastics - which also gets the name from a type of horse sport where a rider tries to stay on top of a horse while it is "bucking." His initial phrase is a play on the word "partner", which is pronounced "pardner" by cowboys.
Buck is an olive green horse with a light brown mane and tail. He has grumpy-looking eyes which would suggest he is a cranky, but as a jock villager he would be friendly. He wears an Eight-Ball Tee, which reflects on his jock personality. His muzzle and hooves are white and the insides of his ears are orange.
Below is a brief description of the jock personality. For more information, click here.
Buck is a jock villager, which means he will often conflict with lazy villagers, because of their lack of exercise. He will also question snooty villagers on their weight, angering them. He will love to exercise and stay fit.
