A nip bush is an excessive and unprecedented amount of hair that circumscribes the areola and gives the chest an appearance of two hairy pacifiers hanging on a wall.
Nip bushes are sometimes displayed as a sign of pride by twenty-something hipsters, men who wear sandals in public, and other people of questionable sanity.
Person 1: Hey, check out my nip bushes!!!
Person 2: Does anyone have holy water or a machete ?
