noun
haunch
HAUNCH/hɔːntʃ/
The part of a body around the hip and upper thigh, especially an animal's hindquarter.
The horse's haunch includes its rounded hip and muscular upper thigh.

Etymology
Old French hanche already named the hip and thigh. The English word preserves that regional body sense, covering the hip, buttock, and upper thigh rather than just one joint.
In context
Like a pack of hounds on the very haunch of a deer the English rushed yelling for the oriflamme.
