Memes and idioms
Wikisimpsons - The Simpsons Wiki
A meme is something that spreads rapidly, becoming well known, usually around the Internet. The Simpsons has spawned a couple of memes over the years. An idiom is something that originated from something like a TV show, book, movie etc. but has became commonly used.
"That's a paddlin'"
Dead Bart is a Creepypasta that has become well known over the Internet. Many fans have been led to believe that it is real, although it is not.
The goggles do nothing!
Originating from the quote by Rainier Wolfcastle "My eyes! The goggles do nothing!" from the episode "Radioactive Man", the quote has been shortened to simply "the goggles do nothing". It is now a popular catchphrase used for conveying the horror of having seen something unwanted.
"Milhouse is Not a Meme"
The phrase "Milhouse is Not a Meme" a paradoxical statement and a well-known debate on 4chan about what makes an Internet meme and what doesn’t, using The Simpsons character Milhouse Van Houten as an example. Since the birth of the debate on 4chan in 2005, the phrase has been typically used to initiate a chain post of recursive nature. Due to its recurrence over time, "Milhouse is not a meme" is often referred to as a forced meme.
X Y is X
X Y is X (replacing "X" with a word and "Y" with another word) originated from the season 11 episode "Grift of the Magi". In the episode, Ralph said the phrase "fun toys are fun". This formula, also called "Redundant Adjective is Redundant", became some sort of a meme.
"You, sir, are and idiot"
"You, sir, are and idiot" is a slight corruption of the phrase "You, sir, are an idiot" said by Krusty the Clown in the season 9 episode "The Last Temptation of Krust". The "d" was added to the end of "an" by a 4chan poster to add an additional layer of irony.
"I must go, my people need me"
Taken from a line that Poochie (voiced by Roger Meyers, Jr.) said in "The Itchy & Scratchy & Poochie Show", "I must go, my people need me" has achieved meme status. The quote came when, to write Poochie out of the show, they made Poochie an alien and said that he had to go back to his home planet. The frame then went upwards, simulating Poochie flying and then it was stated that Poochie died on his way to his home planet.
The misquote of "I must go, my people need me" as well as the "planet" variation are often edited onto pictures of someone in the air, looking like they are heading upwards into space.
Cheese-eating surrender monkeys
While not originating from The Simpsons, meh has been thought to be popularized by the show.
D'oh has been added into the Oxford English Dictionary. It is commonly used by people both over the Internet and in real life.
