Kabete MP Ferdinand Waititu has now included Babayao to his official name.
The controversial legislator’s decision to adopt his nickname was made in a Kenya Gazette notice.
The notice was published on his behalf by J.W Wanjohi and company advocates.
Waititu started using the name Babayao while campaigning for the 2013 General elections to date.
Babayao is a sheng word that means tough.
The sheng word Babayao gained popularity after mucisian Jua Cali released a hit dubbed Baba Yao in 2011.
