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.

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
