e-holla 

An brief electronic shout-out to a friend or family member when one is time-challenged - in order to at least touch base. From electronic + holla. Similar in its construction to e-mail (electronic + mail). An e-holla might also be considered a quick response to e-mail or other form of electronic communication. See holla-back.

I hadn't seen my sister for a while so I texted her a little e-holla on my way to the airport.
