The intention is likely to:
* Emphasize the greediness: "Hegreedypigreedy" sounds more exaggerated and comical than just saying "greedy."
* Connote piggishness: Using "pig" implies someone who is obsessed with food and material possessions, similar to the stereotype of a pig.
However, it's important to note that using this word might be considered informal or even offensive in certain contexts.
