Joongdoker

Shippers who disrespectfully comments "I like this <insert ship> better", or "I only see them as siblings" (despite being not siblings), or insulting other ships under a post designated for it, just to invalidate other people's happiness instead of leaving them alone.
Term can be used to any rude shippers, not limiting to Joongdok shippers.

Artist: *posts a beautiful fanart of Character A and Character B*
Joongdoker, out of nowhere: eww Character A and Character B ship?! I only see them as siblings. I prefer Character A and Character C together, draw them instead
