Charlyboy to join 2 face nationwide protest too says our mumu don do

It seems like you're referencing a popular Nigerian phrase "Our mumu don do" which roughly translates to "Our foolishness has been done" or "We've been foolish".

So, it appears you're saying that Charlyboy, a Nigerian musician and activist, is planning to join the nationwide protest led by 2Face Idibia, another popular Nigerian musician. The phrase "Our mumu don do" is likely being used to express that this move is a sign of foolishness or a mistake.

Am I correct in my understanding?
