Ert indicates that something is stupid. Kind of like "DUH", or a more tolerant version of "that's so gay."
Ert! You are so dumb!

(n.) Used frequently inside circles of theme park/roller coaster enthusiasts, it is an acronym meaning "exclusive ride time." For clubs and organizations, the park will open either allow members in earlier than the advertised time or allow them to stay in the park after the advertised time. Not all the rides will necessarily be open, however the ones that are are usually the high-profile, E-ticket rides.
At this year's event, we get into the park at 8:30 - that gives us two whole hours of ERT!

I have started a movement to get this word into the dictionary, I'm not sure if it would be considered advertising to put a link to it on here, but here's the site: http://www.areyouert.com
A young man was sitting in a reclining chair, contemplating the nuances of the universe, when a strange bit of linguistic pondering suddenly befell him:
I am sitting in this chair, yet I am still able to move. Am I ert? The answer eluded him as he sat, his mind working feverishly on the problem. He thought: if I had some sort of debilitating disease, I would be inert while in this chair, but alas I do not. I must be ert, I have to be.
