Turns out it wasn't.
According to BBC trending, the picture was captured by Heena Pranav, a 28-year-old doctor who lives in Chicago. Back in 2012 she was a medical student and she'd travelled to Gulu, a city in northern Uganda, to help an aid project for women traumatised by the country's war with the Lords Resistance Army.
And the viral image was posted to Reddit three years ago by a man in Texas who spotted the amusing photo on the Facebook page of a friend.
BBC trending wrote, "The first issue raised by memes like this is one of privacy. We haven't yet found the boy or his parents, and we don't even know if they are aware of the image going viral. We've chosen to publish the picture here because it has already been shared so widely and to highlight the debate it raises."
The child in the photo wasn't connected to the aid project - Pranav says she met him at a local market and guessed he was about two or three years old.
"I was with a group of other medical students at the time, we were walking around and I saw this little boy, he seemed really sweet," Pranav told BBC Trending radio. "His mom was nearby working in the market. I went up to him to play with him and say 'hi'… he was the most animated child I've ever met."
The boy didn't speak English, and Pranav doesn't speak the local languages (which include Luo, Swahili and others), but their brief encounter was captured on camera by another member of the group. Pranav says she hadn't even heard of Reddit before her friend posted it on the message board and it went viral.
"I can't imagine this would have happened," she said. "I wished the kid and his mom could have known about it and somehow benefited from it, because I do think he was exploited in the process."
Her misgivings are shared by others working in the aid field. Martine Jahre is vice president of Students and Academics International Assistance Fund, a Norwegian NGO which is famous for making viral videos that make fun of the way charities campaign for aid to Africa, often using poor-looking children in advertisements.
"It's difficult for us to be the moral police and say that's not very funny," she says. "But I think people need to think more about what they're sharing and the messages that it gives.
"You wouldn't like it if your own kid became a meme that people made fun of all over the world. It really says a lot about how we think of 'us' and 'them'."
But the picture has also been deployed in different ways - with some Africans themselves using it to criticise Western ideas of their continent. A few have used the picture to poke fun at media coverage of poor countries:
Meanwhile BBC Trending is keen to find the child - so if you know him or his family, send an email to firstname.lastname@example.org.
