M@rt 

M@rt is someone on an internet forum that talks more than three times worth the amount that people actually listen to said person. M@rt is quick to start a flame war, and just as quick to lose by sheer lack of wits.

Poster1: Hey, I just got a new puppy this weekend! Here are some pictures.

M@rt: Your dog is stupid. I hope you didn't pay anything for that ugly thing. Why don't you get a real camera? No one cares about your dog noob.

Poster1: Noob? I'm the site administrator.

M@rt: .........

S-M-R-T 

In "Homer Goes to College," Homer gleefully sets his high school diploma aflame, while singing, "I am so smart, I am so smart, S-M-R-T, I mean S-M-A-R-T!" Behind him his living room is going up in flames.

The now legendary "S-M-R-T" line was actually not in the script and was a genuine error by voice actor Dan Castellaneta. However, the error was so much in Homer's character that they chose to include it in the finished product.

People now chant either "S-M-R-T" or "I am so smart, S-M-R-T", particularly when they're feeling stupid, celebratory, or both.

S.M.R.T. 

A nice way of saying that someone is so stupid, that they don't even know how to spell smart.

"I'M S.M.R.T.! YAAAAAY!!!"
