Yeuk is a 15th century Middle English word used by the Scots meaning "to itch". When not used as a verb, it is may be used to identify a particular sensation, i.e. the irritation of nerve endings in skin or mucous membrane that provokes the desire to scratch oneself silly if alone or look for a speedy exit if one is in mixed company. It's also a popular name for the parasitic disorder "scabies". See also Diseases.

An actual syndrome or more commonly an obstetric maneuver used for a breech delivery of an infant. One of my co-workers years ago typed "smelly feet syndrome" in the report (she thought that is what she heard dictated) and the OB doc came by to enlighten her (as well as the rest of us), and not too nicely. He felt she should have asked or at least correlated it with the type of report she was typing. It is funny though, isn't it? I still kind of like "smelly feet syndrome", even to this day.
A bellyache or butterflies in the stomach.
While in utero, a person forms an extra nipple and is affected by this for the rest of its life. Mostly from being made fun of on the high school sports team as "triple nipple". See also Body.
