Tag Rag, and Bobtail
The vulgus ignobilë. A “tag” is a doe in the second year of her age; a “rag,” a herd of deer at rutting time; “bobtail,” a fawn just weaned.
According to Halliwell, a sheep of the first year is called a tag. Tag is sometimes written shag.
“It will swallow us all up, ships and men, shag, rag, and bobtail.” —
