A singleton is the name associated with women that only have one nipple. The name originated from England, when a girl by the name of "Singleton", who was later found to be mentally challenged, was found running down a busy motorway completely naked. The most distinguishing feature of the crazed girl was the fact that she had a large right breast and a "deflated" left which did not show any form of nipple. Thus, the term "Singleton" was born.
"Holy fuck bitch, you got a damn singleton, get off my cock!"
