It's Sam, the kid who's been a non-poopchute from the jump. He's not calling anyone out.
Friendly excrement-talking with his boys, knowing that Nickerson was not playing full-speed. Modest ball-breaking.
Wait, I didn't think he meant it "seriously" serious. I knew he was taunting him. I was just thinking "Yeah, well that's shitty cuz the guy literally couldn't stop you, what's he gonna do other than watch you coast by?"
I didn't think Sam was being an poopchute. I'm not even sure Sam's capable of being an poopchute.
