[PLEASE HELP] Why did Royce diss Common?

[Kobe Bryant]

On the Slaughterhouse album he said that he lost respect for Common as a man. Why?

If I refer to you as a girl *****z'd call this Common
... I'm through as a fan
No disrespect to music, I'm talkin to you as a man

[Third Degree MM]

I heard some mixtape from Royce, I think it was The Bar Exam. Dude is just angry. Thats why he probably did it.
