look up any word, like sweetest day:
A "Grove Rat" is a person living in the poor Southeast Dallas Inner city neighborhoods known collectively as Pleasant Grove.

The term was first used in the 80's due to the living conditions of Pleasant Grove slums where many Rats live and that a Rat would do anything to survive, as in, a human "Grove Rat" would also do anything also to survive.
Man, ain't nothing but a bunch of Grove Rats live off of St. Augustine Road.
