1) Less ghetto version of
holla back, meaning to respond to a person at an unspecified later time.

holler" is a country term for a valley, a bastardized version of "hollow").

After the fifth time Judd had to blow a homeless guy for coke to keep him going through an all-nighter at his terrible

Shitville, Oklahoma.
