Watermelon Sugar is a metaphor for something that just does not exist. It seems plausible, because artificial watermelon flavor usually has sugar added. But an actual watermelon has no sugar, in fact people add salt instead. So it could also possibly be an ironic example that is substituting sugar for salt .
She is just too good to be true, she's watermelon sugar.

She appears to be sweet, but at closer taste most definitely salty.
