A phrase commonly used to refer to someone who is hungry, tired or ill. Can be used to describe general mental or physical discomfort. Much like it's closely related counterpart "
under the weather".
First usage took place in early 17th century England. During
the Black Plague many people would be referred to as "under the buggy" or "under the horse". Evolving to present day we now use the more present term "car".
