Ochlophobia is a noun that refers to an extreme fear or dislike of crowds or mobs.

The prefix O-C-H-L-O is Greek in origin and it means crowds. P-H-O-B-I-A — also Greek — means fear. Here’s an example of our word of the day in use:

With my ochlophobia, it was concerned that the crowds for our band would make me uncomfortable. But it turned out the crowds were so small there wasn’t anything to fear.
