Piss Chunks

Bite size pieces of watermelon. When eating watermelon properly, one usually uses a knife and fork and eats chunks of watermelon which are like bite-size pieces of the fruit. Watermelon is mainy water so eating a lot of it causes one to urinate frequently, the same as drinking beer does.

"Son, put some salt on those piss chunks, and you won't have to go so often."
