I'd like to think that this guy is yelling at these trucks for some greater calling in life.

Almost like a higher power hit him with an epiphany while he was sitting in his living room, shirtless, pantless and hot pocketless.

A voice from above told him, "Yell at these trucks, because if you don't do it . . . who will!?"

Of course he could be just some bored redneck with a video camera.

Thanks to Gorillamask and Break for this.
