This dude wasn't having any of it.
Motorcyclists have a thing for yelling at drivers, aka cagers. Oftentimes it's for distracted driving or just not noticing the motorcyclist is on the road. Sometimes the rider is completely in the right and other times they go way too far. In this case the rider appears to be in the right as he's telling the minivan driver (who almost hits him) to get off his phone. But the driver isn't having any of it, especially the swearing. He pulls a pretty big power move, shutting up the angry biker in a matter of seconds.
We won't spoil what happens next, but just know that if you ever find yourself on the receiving end of a motorcyclist's complaints this tactic should shut them up.
