Get the seabiscuitmug. NOUN. The act of going at it with a girl from behind (doggie style) whilst slapping her on the ass only after kicking her in the leg or arm (your preference) making her a "gimpy horse".

Get the seabiscuitmug. When you are fucking a chick from behind and you are about to cum you neigh like a horse nice and really loud, so as to cause some sort of confusion so that she looks back at you and then you cum in her face.

Get the Seabiscuitmug. A person who resembles a horse. This can be in several ways such as long hair similar to a mane. It can also include making horse like face gestures such as chomping/licking of the lips and mouth. Another way can be stomping and clomping around in an aggressive manner.
