How I learned the Word "Bonga"

Two Sunday ago I at a lot. I started my day at a trendy cafe followed quickly by a delicious Ethiopian lunch. I had been feeling a bit like going to a salsa lesson but decided I preferred to stay closer to home. I knew there was a slum down the street with a market and the weather was nice so I decided to take a walk. Approximately twenty steps into the slum I was surrounded by 20 very excited children all asking "Muzungu! How are you?" (Muzungu means white person in Swahili). Almost every child in Uganda knows this phrase as well as "I am fine" even if they speak no other English. I would soon discover that this was the case for most of the children who were crowding around me. After a few failed attempts at communication I decided I would continue my walk. To my surprise the children decided to walk with me, grasping for both of my hands. I can't imagine how ridiculous it must have looked to the local adults to see a blonde mzungu walk down the street with so many children around them. After heading back on my walk I stopped near the exit of the slum and wasn't sure what to do with the kids. First I spoke with the ones who understood English and then proceeded to highfive most of them. I then danced a little bit which didn't seem as popular. So I did what I always do when everything else fails, I fist bumped (props) them. Immediately they all excitedly screamed "Bonga!" As I walked away some of the older children prevented the younger ones from leaving the slum with me. And that's how I learned the word Bonga

Note I assume Bonga is either swahili or Lugandan, no sure which.
