a rock that committed so hard to being a rock it earned a name
means a large rock, especially one worn smooth and rounded, too big to easily move and resting on the ground or in a stream.
from From a Scandinavian source — compare Swedish dialect 'bullersten,' a big stone in a stream, where 'buller' means a roaring or rumbling noise and 'sten' means stone. So a boulder is, at heart, a 'noise-stone' — named for the racket water makes tumbling it along. English borrowed it as 'bulder stone' before trimming it down to plain 'boulder.'
