Trochee Fixation
If you Huffman-coded all the 'random' things everyone on the internet has said over the years, you'd wind up with, like, 30 or 40 bytes *tops*.

[edit] Explanation

A trochee is a type of metric foot. A foot is a measure in poetry, it consists of stressed beats and unstressed beats. A trochee is a foot which consists of one stressed beat followed by an unstressed beat. "Trochee" itself is an example of this as you stress the first syllable and don't stress the second syllable ("TROH-kee".)

Trochee fixation is supposedly caused by people experiencing rushes of dopamine when they hear or speak trochees during their youth. Due to the rush of dopamine they become more fixated on trochees. In the endless quest for dopamine, they continue to search for trochees (typically on the internet) while also producing more places to encounter trochees meaning more fixation for others with the disorder. Megan proposes a "radical trocheeotomy" which appears to be a type of psychosurgery due to the erasing of memory. Cueball misinterprets Megan's intent as a "tracheotomy", a removal of the girl's vocal cords, of which he is in favor.

Megan proceeds with the trocheeotomy, but it sadly does not have the intended effect. Though the previous trochees have been removed, the girl immediately generates new ones: "BAN-jo," "TUR-tle," "JET-pack," "FER-ret," and so on. The correct way of removing the fixation would be to alter mesolimbic pathway. Megan, not realizing this, succumbs to attempting to removing the girl's trochee fixation via cranially-applied brick. Depending on how hard the girl is hit with the brick she may have memory loss and potentially forget all the trochees she knows, but if this method is carried out she will have significant brain damage and will likely start fixating on trochees that she hears.

There are references to Teenage Mutant Ninja Turtles and Mighty Morphin' Power Rangers, both of which are examples of actual, trochaic TV show titles. Additionally, there is a reference to sci/fi author Neal Stephenson who has written Snow Crash, Anathem and many other books.

"Jetpack ferret" could be a reference to 20: Ferret, although the ferret in question only had wings.

Huffman coding is a lossless data compression algorithm that works by recording a specific string and then only recording that the string is repeated a certain number of characters later on until eventually it only contains a "dictionary" of unique substrings and then mentions of where those substrings repeat. In highly repetitive data this can cut down the file size immensely, which is what Randall is implying by saying you would only end up with 30–40 bytes. Most of the "random" stuff said on the Internet has been said before.

Trochee and other types of poetry "feet" is the subject of 1383: Magic Words, and the trochaic form is explored further in 1412: Teenage Mutant Ninja Turtles.

[edit] Transcript

Girl: Robot ninja! Pirate doctor laser monkey! Narwhal zombie badger hobo bacon kitty captain penguin raptor Jesus!
Megan: We'd been seeing this brain damage for years, but only recently did our linguists identify the pattern behind it.
Megan: The patients fixate on animals and types of people whose names are trochees (two syllables, with the accent on the first).
The malfunction causes a rush of dopamine whenever these trochees are heard or spoken.
[Chart shows "internet" and "brain," with arrows marked "trochees" traveling both ways between them. An arrow marked "dopamine" loops from the brain back to the brain.]
The warning signs appear in childhood:
[Child sits in front of TV.]
Child: Yeah! Mighty teenage morphin' ninja power mutant turtle rangers!
Social reinforcement focuses the fixation on a few dozen words.
Cueball (off-panel): Is there a cure?
[Girl is reclining under a big machine pointed at her face.]
Megan: We're about to try a radical trocheeotomy.
Cueball: Rip out her vocal chords? I'm in favor.
Megan: No, we're modifying her vocabulary* to erase the words she's fixated on.
*Digitoneurolinguistic hacking! It's totally real! Ask Neal Stephenson.
Megan: Either the gap will be filled by normal words, or she'll just generate a new set of trochees.
Megan: Here goes.
[She pulls the lever on a large panel.]
kachunk bzzzZZZZZZ
[Girl is waking up.]
Girl: ...GzZhRmPh ...
Girl ...banjo turtle!
Girl: Jetpack ferret pizza lawyer! Dentist hamster wombat plumber turkey jester hindu cowboy hooker bobcat scrapple!
Megan (off-panel): Sigh.
Megan: Time for plan B.
Cueball: Someone get a brick.

Bad advice mallard would like a word with you. Davidy²²[talk] 07:08, 17 April 2013 (UTC)

"Cowboy" but no "Bebop"? (Also a real cartoon show, albeit an adult anime -- NOT FOR KIDS.) I'm disappointed. --BigMal27 // 11:55, 18 June 2014 (UTC)

Why... why does the little girl say "hooker" at the end of the comic? 13:16, 18 June 2014 (UTC)

Why not? Perhaps she's seen some television cop shows which use the term. Or perhaps she likes rugby (it's the name of one of the playing positions). Grutness (talk) 01:56, 26 July 2015 (UTC)

In particular I think the Neil Stephenson reference is to Snowcrash, where hackers are able to transmit a linguistic virus that disrupts speech patterns into what appears to be intense aphasia or glossolalia. According to the science* of the book, a similair technique could be used to manipulate the brain in a variety of ways, including a 'trocheeotomy.' (talk) (please sign your comments with ~~~~)

The current explanation mentions a reversal of the stress pattern at the end, but that doesn't happen. As discussed in the comic, the girl has simply come up with a new list of trochees. 22:54, 18 June 2014 (UTC)

Trochee is autological. 11:22, 30 May 2015 (UTC)
