Kidney

Kidney - south of the chesticals; north of the testicals, these abdomnicals seem to have no obvious function. A waste of human tissue. Not unlike the distributor cap of an '94 probe, these babies are just waiting explode or malfunction.

Often the source of complaint when wimpy ex-boyfriends/unsuspecting bachelors awake in a discount hotel tub of fresh ice next to what appears to be a sincere written apology - kidneys are, however, a notable asset to the black market.
