For those that don't want to watch the full 31 min video I took some notes. So basically:
▪There was no tension between the groups before the battle
▪He didn't know that Mooks mother had passed away about 3 months prior to the battle
▪He bumped mook while he was rapping because Mook was trying to push Brizz back to make some space for him to get to T-top but Brizz purposely wasn't going to move
Brizz says he didn't mean to bump Mook that hard
▪After Brizz bumps Mook, Mook tries to push Brizz back but Brizz grabbed his arm because he was losing his balance
▪Mook swung on Brizz because he thought Brizz was about to swing on him after grabbing his arm
▪Brizz apologizes to the culture and to Mooks mother
▪Brizz also states he only did these things because that is what happens in Battle Rap, It was never his intentions to start a fight by calling Mook's mother a B*tch or bumping Mook
