There was a time when Black people would call that c00ning. Especially with those facial expressions he was making.
If it turns out this is fake and the chip wasn't salty at all and he's just acting a fool for views that would be considered a form of c00ning.
That's just the physical reaction to eating an extremely salty chip. That'd be like if there was a challenge to eat a lemon and expect a person to remain stoic.
