look up any word, like plopping:
A horse who is constantly sleepy. Never moves unless forced, eats only when fresh food has been placed under it's mouth and when it makes a bowel movement said horse never lifts it's tail. Hence not only a very sleepy horse, but a horse that has shit all over it's rear end and always drools. It sucks so bad that you could put Christmas lights all over it and it would matter. It would just make it a festive sleepy horse.
Basically it is the act of being a waste of life.
