Don't know what it means, and I haven't used the word garabato in a long, long time.
By the way, Garabato Sackey was a legendary Dominican baseball/softball player.
In this case the word garabato doesn't means scribble, people in DR call garabato the wire where they hang meat to dry up on the sun.
The phrase is used by Dominicans when trying to say that something is still available but not because of lack of offer.
