Slang in the World of Avatar

Slang is a term that is commonly used in everyday language but not considered an official word. It includes exclamations and untraditional insults. There are several types of slang in the World of Avatar, particularly in the Fire Nation.

Terms

 * Bite us in the blubber - A term used to indicate that a specific action will have consequences later on, or the equivalent of "come back to haunt us". Sokka said this to Aang when the Avatar rudely told Joo Dee off.
 * Colony Trash - An insult directed at Fire Nation colonists who live in the Earth Kingdom. It was used by Hide to insult Aang.
 * Dancy Pants - A term used by Toph to refer to Aang's dancing.
 * Dirt people - A Fire Nation insult directed at people with Earth Kingdom heritage, especially earthbenders. It was used by Master Kunyo to insult Toph Beifong, and later on he used the term in an official complaint as well.
 * Flameo - By context, has several definitions including "hello", "goodbye", and "great". It was used by Aang while attending a Fire Nation school, much to the confusion and amusement of others. Used before the Hundred Year War, the term had fallen out of everyday use by 100 ASC.
 * Flying hog monkeys - A phrase used by many members of Team Avatar in unpleasant or unlucky situations. A varied form is "bleeding hog monkeys", used by the pirate captain upon seeing Team Avatar take off with his ship.
 * Gasbag - A word used to refer to someone who talks too much. Zuko described his uncle, Iroh, and an Order of the White Lotus member as such when they were talking amongst each other and Zuko could not discern the meaning of their conversation.
 * Glow it up - A phrase used to refer to going into the Avatar State.
 * Hotman - A term for someone from the Fire Nation or the equivalent of "sir". Aang used this term to address strangers until he realized it was drawing attention. He later called Zuko "Sifu Hotman", much to the firebender's dismay. The generic term became outdated by 100 ASC.
 * Hullabaloo - A term used by Aang's music teacher at the Fire Nation school to refer to Aang's dancing while playing the tsungi horn.
 * Jerkbending - A term used by Sokka as a synonym for firebending to express his dislike for the bending art.
 * Lily livers - An insult used by Toph on her metalbending students. It is the equivalent of "easily frightened".
 * Meat head - An insult used to imply someone's stupidity. It was used by Katara to refer to Aang and Sokka who wanted to take the easy way out.
 * Monkey feathers - A phrase used by Aang when events are not favorable. Variations include "double monkey feathers" and "monkey feathers on top of monkey feathers".
 * Nut brained - An insult with the equivalent of "stupid". Katara used it while yelling at her brother.
 * Oogies - A term equivalent to "yuck" or "gross". It was frequently used by Sokka in the events surrounding the Harmony Restoration Movement in reference to Aang and Katara's romance. Toph showed that it was comparable to licking someone's hand.
 * Snoozles - A term used to refer to someone who is either sleepy or still asleep. It was used by Toph to describe Sokka when he complained that her and Aang's earthbending training was depriving him of further sleep.
 * Snow savages - A Fire Nation insult directed at Water Tribe members. It was used by Master Kunyo to describe Sokka in an official complaint, thus it has to be a term that is common in the Fire Nation.
 * Sugar Queen - Another slang used by Toph. Depending on the tone in which it is said, its meaning varies from an insult to a term of endearment with a mildly mocking connotation. Usually it means "goodie-two-shoes", or "know it all".
 * Sweet sugar cakes - Avatar Extras states that it is the Avatar equivalent of "babe". Ty Lee addressed Azula like this while attending Chan's party.
 * Twinkle Toes/Fancy Dancer - Terms used by Toph to describe Aang being light on his feet.
 * Uncle Fatso - An insult used by Azula to refer to her uncle Iroh.
 * Working my arrow off - A phrase of Air Nomad origin, it refers to the airbending master tattoos. It means to work very hard; Aang used it to indicate to Sokka that he had been training very hard, and thus deserved some time off.
 * Yip yip - A term which is the equivalent of "go". It is used to command a flying bison to fly.
