Rainmelon
A way to describe someone who hides the details of their romantic relationship to their friends. This includes not showing photos, or even sharing their partner's name. This person could be described as rude and disrespectful to their friends(sasses them a lot).
Me: She is such a rainmelon
Other person: Yeah she is so rude for not even letting us now who he is.
