look up any word, like bae:
Where someone goes on youtube, accounts for the number of dislikes of a video, then makes a sarcastic quip to explain the reason why the video is unliked.
1000 people like the new Christmas video and 20 dislike it.

Person comments, "20 people are Grinches".

This is repeated over and over as a top comment for many videos on youtube and thus a dislike bar cliche.
