|This gorilla's mother not only raised him, but continues to dress him.|
Google seemed like the easiest place to start looking for an appropriate name. I googled several combinations of words including "abandonment" and "African word" and "unwanted" and "baby." Nothing significant came up except for this haiku. When I tried "African" and "orphan," I discovered a song called "Baayo" about a child with a dead mother. Although that isn't the case here, since the gorilla's mother, Monifa, is only emotionally dead and not physically dead, I still think Baayo, which apparently means orphan, sounds pretty good.
Next up, the second best source for information: Wikipedia. Consulting Wikipedia's page of South African slang, I found words for "shit" and "mother" which add up to Kak Mallie. I think that would hold the mother responsible in a way that Baayo does not, and it also has a nice ring to it.
If we wanted to dabble in a bit of symbolism, we could relate the name back to the idea of a white elephant, which means something unwanted. Using Google and Wikipedia to find African words for white elephant, I came up with this: Umlungu Loxdonta. That's a little cumbersome. But, then again, motherhood would have been cumbersome, too. Isn't that right, Monifa?
