To the plethora of writeups for this linguistically ambiguous word, I add one more piece of pop-culture trivia.

"Chunk" was also the nickname commonly used to reference Lawrence "Chunk" Cohen in the 1985 teen-flick, Goonies. Portrayed by actor Jeff Cohen, Chunk was the roly-poly, generally jovial kid in the film (even when incessantly teased), whose philia-styled affection for the deformed "Sloth" was well-documented.

While his own name has faded somewhat into obscurity over the years, Jeff Cohen's performance in his role as Chunk, has virtually cemented, both visually and culturally, the hilarious-yet-humiliating "Truffle Shuffle" dance into the collective American mind and lexicon.
