Very large, lumpy buttocks with the appearance of being molded from large scoops of cottage cheese. Spandex does much to liberate and define the 'chunk' in many chunk butts.
Wow, look at that chunk butt walking across the street. (I first heard this in the mid-80's in Los Angeles, and that is an exact quote.)
