Shamakakaka is similar to Soulja Boy's 'Yah!'. It's a word that you use when your tolerance has maxed out. It's a combination of 'Shut Up!', 'Get Out Of My Face!', & 'I'm Through With This Matter!'. It originates from A WhiteWood Entertainment video starring Dave Chaney titled 'Shamakakaka'. The word started in Detroit and because of the video going viral, has spread nation wide.
