In reference to his previous line about causing an uproar, he’s saying he has touched on (spoken on) everything to do so except children (pun intended). The little boys mention sounds like a ‘stab at Michael’ because Michael Jackson was accused of child molestation. (In fact, Eminem avoided getting sued because of the ‘that’s not a stab at Michael’ lines.)

Wordplay on :“stab at Michael” and “I’m just psycho.
And but — butt, another reference to child molestation
