A user on a chatroom or forum who, for whatever reason, decides they're a moderator or admin, even though they're not. These users will yell and scream at other users who they believe are breaking rules, telling them not to break said rules. They will often call on the real moderators and tell them how to deal with the supposed rulebreaker. These users are probably 10-15 years old and have a bit of a superiority complex.

These users think they mean well, but are actually just a giant pain in the ass and act as though the real moderators are incompetent. This often involves freaking the fuck out over the SLIGHTEST breach of the rules - or often when there is NO breach of the rules.

Often, the user is simply trying to get promoted to being an actual moderator. But what happens 99.9% of the time is that they get banned themselves. What is 110% certain, however, is that this user will NOT be promoted.
User on chatroom: Oh shit
Backseat Moderator: NO CUSSING!!! MODS, BAN THIS FOOL!!! BAN HIM!!! HE CUSSED!!!!!
Real Moderator: Cussing is allowed on this chatroom, dipshit.
(Backseat Moderator has been banned by Real Moderator for being a giant pain in the ass)

Get the Backseat Moderator mug.
A message board user who, though they do not actually hold the position of moderator, has some twisted sense of duty which they feel they must fulfill. This user seems to believe that the moderator is a retarded monkey that needs to be led around by the hand and told which threads need to be locked or deleted.

The backseat moderator can often be seen jumping up and down and frantically waving their arms, trying to draw attention to a thread which surely is offensive and stupid to the highest degree and must be locked immediately. In reality, the real moderator has probably looked at the topic and seen nothing which crosses the line.

The backseat moderator may also be a backseat administrator, letting everyone know which users need to be banned. Though the backseat moderator is irritating, there is nothing which can be done unless the real authority on the board takes matters into its own hands, and ejects them from the board in a hilarious example of irony.
"This topic is dumb. Lock it please!"
"Ban this guy, he's a moron!"
