You're on the right track. What kind of phrase, sentence, or clause is this?

Foreman threw a wild left. Then a left, a right, a left, a left, and a right. Some to the head, some to the body, some got blocked, some missed, one collided with Ali's floating ribs, brutal punches, jarring and imprecise as a collision at slow speed in a truck. . . .

Across that embattled short space Foreman threw punches in barrages of four and six and eight and nine, heavy maniacal slamming punches, heavy as the boom of oaken doors, bombs to the body bolts to the head, punching until he could not breathe, backing off to breathe again and come in again, bomb again, blast again, drive and steam and slam the torso in front of him, wreck him in the arms, break through those arms, get to his ribs, dig him out, dig him out put the dynamite in the earth, lift him, punch him, punch him up to heaven, take him out, stagger him—great earthmover he must have sobbed to himself, kill this mad and bouncing goat.
