Matt really got paranoid after she hit him with a butt chunk.
We aren't going to sit here and do the reach-around butt chunk

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.)
