Nairobi...is off the chain. I only spent two days there, but the energy and feel is in great contrast to the coast. First of all, everyone speaks English, and their Swahili is 'chopped and screwed', so much so its become its own sub-genre of Swahili called Sheng. Here are a couple examples of Swahili slang or Swahili-English mixture:
niaje?= how are you?
nimekumiss= I miss you
kujienjoy= to enjoy yourself
More can be found at this online Sheng Dictionary
Anyway, I was hanging with Silas (my Swahili teacher's nephew) and his friends. Much respect and appreciation to him for showing me around.
