Would you please translate this underlined part of lyrics in the movie , "The school of rock"?

I can't exactly see what the underlined mean.

?? Oh, you know I was on the honor roll
?? Got good grades Ain't got no soul
?? Raise my hand before I can speak my mind
?? I've been biting my tongue Too many times
?? And then that magic man Took you away
?? Do what magic man do
?? not What magic man say
?? say What?
?? Now, can I please have the attention of the class?
?? Today's assignment;

?? Kick some ass!
