Not necessarily what I thought it meant. But I like this definition, found on the Urban Dictionary:

Staying true to yourself, your faith, your life and constantly seeking the truth. By keeping it real you are authentic and do not follow the geopolitical or corporate economic norm, but you strive to develop a norm that is centered on peace, truth, and unity.

but this and this definition are also interesting and worth some research.
