I have to admit, though, there aren't too many people who would threaten to boot your balls up into your medulla.
Although I am left wondering just what kind of kick this would be:
Medical uses include:
* Medulla oblongata, a part of the brain stem
* Renal medulla, a part of the kidney
* Adrenal medulla, a part of the adrenal gland
* Medulla ossea, the marrow inside a bone
* Medulla spinalis, an alternative name for the spinal cord
* Medulla of ovary
* Medulla of thymus
* Medulla of lymph node
* Medulla (hair)
Non-medical uses of the term include:
* Medúlla, a 2004 music album by Icelandic singer Björk
* Medulla, Florida, a U.S. city
* Las Médulas, Ancient Roman gold mines in León, Spain
* Medulla Grammatice or Medulla Grammaticae, a fifteenth-century Latin–Middle English dictionary.
Probably the latter. He's probably got a collection of them.
