to creep. (1) To move with the belly to the ground without legs; as a worm.
(3) To move forward without bounds or leaps; as insects.
(6) To move timorously without soaring, or venturing into dangers.
Paradise Lost is admirable, but am I therefore bound to maintain, that there are no flats amongst his elevations, when it is evident he creeps along for above an hundred lines forever. Dryden
(2) A subterfuge; an excuse.

Bush Tetras: Too Many Creeps (Link)
Note: Pictured in positions (1) and (2) above are representations of types of "creep." Image no. 3 is a "creep machine." The Bush Tetras song is for the ages. Readers will have no trouble summoning and adding their own mental images of other creep forms. Like rust, creep(s) is/are everywhere. No sleep for creep.
