We don't know but chances are high he hears this from his parents or someone at home arguing. The way he says 'shut the fuck up' and 'no bitch' is like two people fighting. Shit just flowed together.
No, you assume this. It's not a high chance at all.
Contrary to the fun belief children learn bad behavior from home and the parents, a child can easily learn bad behavior from other environments. Including but not limited to school itself.
There seems to be this massive misconception bad behavior is likely learned from home and can't be learned elsewhere. Or that children are computers that you can force boot a program.
