Dumploongi 

A nickname given for BTS member Suga, made from the words Dumpling and Yoongi (which is his real name). This nickname is the brand of twitter user @meow_yoongles, as she created the name itself. Know that it is not meant for fetishizing and degrading the member to childlike statures. It is only supposed to be used in an endearing way, and you can see her tweets for the way she uses it.

E.g.: I miss Dumploongi.
(Used in a cute way to say that you are missing Min Yoongi, very much.)
