Wataremelon whut-RR-mell-on noun 1. A large, hard-rinded, sweet, pulpy fruit that has yet to be identified. Not to be confused with Can'talope: a similar type of produce that Fruit Scholars have given up on classifying. "Most will insist that all the most exciting fruit salads are made with wataremelon. Those with true class know that, of course, the most sophisticatedly surprising salads are made BY a wataremelon." -Dyson, Cuban. "Slice of Life".
