Cumquats can be refered to as "balls" or the testes. Because "cum" is sperm, cumquats are what produce sperm to be released for many reasons- such as to make a baby. Cumquats vary in size but they are usually oval and semi-squishy. They are usually 2-3 inches long and most likely are shorter than the penis. Cumquats can be injured very easily and are usually prime targets in fights. Cumquats hang low in the scrotum or "sack" under the penis, around the groin area.
