At 6:54 He says: "Ye moko mofingi batu, ye moko moluki ngai, ye moko motongi batu, ye moko moleli ngai."
Which means: "He is the guy who insults people, he is the guy who is searching me (KoLuka in lingala it means to search, but not only in the way of searching things, but also searching problems, Koluka ngai `to search me` in Lingala it means looking me for starting problem and this is the meaning Bill wanted to give to the sentence.) He is the guy who speaks behind people's back, he is the guy that regrets me. Because I think is about Werra but I am not sure in fact in the beggining of the song he said "Tumba Zamba, lume la foret". Which means Burn the forest lol.
There is a video of the song on YouTube if you want to watch it but check out because the audio is way off
