riser
n.— «The Manx Cat is a tail less breed of cat, but there are a few variations. Some have a hollow where the tail should be, they’re called “rumpies.” Others have the beginnings of a tail, they’re called “risers.” Those with a slightly longer remainder of a tail are called “stumpies.” Finally, those with an obvious tail are called “longies.”» —“Flowers of Sri Lanka: Our first step to the world of flora” by Manoj Dissanayeke Daily News (Sri Lanka) July 16, 2007.
