Code word for Danger as explained in the series "Friends"
Joey: Well, you wouldn't let me in, so I thought you were in trouble.

Chandler: Well, we're not.

Joey: But you called me 'Bert'!? That's our code word for danger!

Chandler: We don't have a code word.

Joey: We don't? We really should. From now on, 'Bert' will be our code word for danger.

Where happened to Joe?
He probably pulled a bert with his hand in a bag of chips.

n: A little piece of shit that no one likes because he's a fucking dick sucker who thinks everything is under him. A Bert will often feel the need to critique anything you happen to say near him. On the plus side a Bert is a very intelligent person who can do many things that others can't. A Bert is very prideful in who they are despite who others may think of them.

v: A Bert is the action of over correcting something in an uncalled for manner. Often times this action is repetitive and continues without the persons consent.
Person: I was looking at Disney the other day...
Bert: Oh Disney sucks, and you know why...
Person: No Bert, why don't you tell us
Bert: Because Walt Disney is Hitler...
Person: Bert just stop.
Bert: Let me finish (insert chuckle)...without his mustache, and to work at Disney you need to surround yourself with white supremacist if you want to stand out. (insert chuckle)
