Mr. Mark James's definitions
To be a nelly bottom is similar to being a piggy bottom, power bottom, or pig bottom. To be a nelly bottom is when you, the gay man, strive to have your anus pounded with another guys penis. Being a nelly bottom means you can take any size, length, width that is thrusted your way. Making sounds such as nelly, makes you a nelly bottom. Not a high pitched moan or even a wimper like some pig bottoms will do, but to make a "Nelly" sound of complete enjoyment. Loving it and making a lower pitched yet steady beat of non stop anal intercourse.
Preston's boyfriend is a huge Nelly bottom, they will fuck for hours and his boyfriend still hasn't had enough of that 10incher.
