Not all of Colombia uses that word - it's more of a thing of an specific region. My parents were born there, but as they were brought to Bogotá in an early age, they barely use it. Though I use it more than them as I feel it conveys more sincerity than the "official" ones (tú, usted).
Weirdly enough, some colombians seem to despise this word or look down on us who use it.
