whiner
Someone who constantly complains about something else and usually hopes that someone else will listen to them. Nowadays, the most common places to find them are on Internet forums or on youtube and they usually will complain and whine on videos or topics about fictional characters or any other part of fiction instead of complaining about real life.
Example:
A whiner is someone that never stops complaining and I just saw one of those on youtube, since that place seems to be infested with them.
