A reference to the custom in small Japanese fishing villages to discipline an unfaithful wife by having all the fishermen ejaculate into a ripe watermelon and subsequently the chatting wife had to eat it. However, some women liked it and purposely sought this discipline so it is now used as an invitation to engage in this fetish.
That girl just received a watermelon in her DM's... You know what that means! Japanese Watermelon is crazy!

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.

The word that’s been stuck at #1 trending for over a year, because the words on the Trending page for this website haven’t been updated in over a year, most likely because Urban Dictionary staff either completely forgot that the page existed, or because they gave up and purposefully abandoned it.
The Trending page is more frozen than a Canadian lake during the Winter. I mean, even if it’s about the Harry Styles song, THE HARRY STYLES SONG “WATERMELON SUGAR” WAS RELEASED IN MAY 2020. IT’S JUNE 2021 THIS IS RIDICULOUS
