Chat Clients

## Pesterchum and Trollian

**Pesterchum** is a chat client used by humans.

**Trollian** is a chat client used by trolls. Despite Karkat being blocked by Jade, and Jade logged out of Pesterchum, Karkat is still able to troll Jade .

### Notifications

Largely the same notifications are used between Pesterchum and Trollian.

When a character pesters someone, the client's chat log will display both users' names, screen name acronyms (in their respective text colors), and the time (24 hour clock). For example, the top of this log between Dave and John  reads:

-- turntechGodhead [TG] began pestering ectoBiologist [EB] at 16:13 --

If the user who instigates the chat is from the Trollslum, the same notification will be sent , except "pestering" is replaced with "trolling", and the troll's entire username will be colored instead of just their acronym:

carcinoGeneticist [CG] began trolling gardenGnostic [GG] at 13:04

When a chum *stops* pestering another chum, the log will display as such :

-- gardenGnostic [GG] ceased pestering ectoBiologist [EB] --

When a chum hasn't ceased pestering their chum, but hasn't posted for a while, the log will display that they've gone idle:

-- turntechGodhead [TG] is now an idle chum! --

When a chum loses connection, the log will display as such :

-- tentacleTherapist [TT] is no longer connected! --

When a chum changes their status, the log will display as such :

-- turntechGodhead [TG] changed his mood to RANCOROUS  --

When a chum sends another chum a file, in Pesterchum Enamel, the log will display as such :

turntechGodhead [TG] sent gardenGnostic [GG] file "explore remix.mp3"

In Pesterchum 6.0, there are hyphens at the beginning and end  of the notification:

-- gallowsCalibrator [GC] sent ectoBiologist [EB] the file "GOH3R3JOHN.G1F" --

When a chum bocks another user, the log will display as such :

gardenGnostic [GG] blocked carcinoGeneticist [CG] at 13:06

### Versions

There are a couple different versions of Pesterchum used between the humans. Despite their differences in apparent age, all of the versions of perfectly capable of communicating with one another.

#### Pesterchum 6.0

**Pesterchum 6.0** is the version of Pesterchum used by John and Rose .

It features a *Chumroll* which lists the user's friends, and a list that lets the user pick a status that reflects their current mood. The statuses Chummy, Palsy, Chipper, Bully, and Peppy all seem to use the same yellow smiling emoji. The last status, Rancorous, is the only status that differs visually; it is red and features a scowling emoji. Changing your status does nothing whatsoever .

Pesterchum 6.0 makes this sound  to notify that a chum is pestering you.

#### Pesterchum 7.0

**Pesterchum 7.0** is the version of Pesterchum used by Dave. It has a more complex art style than 6.0.

Similar to 6.0, this version of the client lets you pick a status. The statuses in 7.0 are mostly different to the ones in 6.0 and have unique facial expressions associated with them, as opposed to only happy or angry.

* Chummy – The standard smiling face.
* Mystified – A surprised face similar to the one shown in the Pesterchum logo.
* Amazed – A more shocked facial expression than Mystified.
* Insolent – A face with a quirky smile.
* Bemused – A face with a wavy mouth.
* Pranky – A sly winking face.
* Smooth – A stoic face wearing sunglasses.
* Pleasant – A simple smiling face.
* Rancorous – Same as the rancorous icon in 6.0.

#### Pesterchum Enamel

**Pesterchum Enamel** is the version of Pesterchum used by Jade. The client application has a header that reads "MUCH SHINIER!" and, appropriately, many of the graphics used have shinier appearances than their counterparts used in other versions of Pesterchum. The font it uses for chat windows  is also much higher resolution.

There are only eight statuses in Enamel—less than the number of statuses in 7.0. They are not named, but by comparing the icons to the icons of the statuses in Pesterchum 7.0, it can be deduced that the available statuses are: Chummy, Pleasant, Mystified, Amazed, Bemused, Pranky, Rancorous, and an eighth status with an unhappy face that is new to Pesterchum Enamel.

Pesterchum Enamel is the only version explicitly shown to have a Trollslum for pestering trolls.

When a new chatlog begins, alongside listing the time, Pesterchum Enamel will also list the date :

turntechGodhead [TG] began pestering gardenGnostic [GG] at 2009-04-12 -- 23:14

This format is also missing the double hyphens at the beginning and end of the notification, as is standard for all the other notifications in 6.0 and 7.0.

## Serious Business

**Serious Business** is a chat client used by humans for serious business , and is downloaded on John's Dad's PDA. It bears little to no resemblance to Pesterchum or Trollian.

The application for Serious Business has an icon of a simple rendering  of a square-headed person wearing a fedora. When opened , the client has a banner at the top with the icon and text reading "SERIOUS BUSINESS". Below is a log of texts sent by other SB users. Texts display the username of the user who sent the text and the time at which the text was sent.
