Atr originated from Torn IRC meaning "small penis" this was because Atr gave a picture of his penis and it was very small, from now onwards people call it an "Atr" when they see a small wienner.

the ATR72 is built by ATR. American Eagle, the regional airline company of American Airlines under the AMR Corporation, refers to its ATR 72s as "The Super ATRs". These models are twin-turboprop short-haul regional airliners. The ATR 42 seats up to 60 passengers, while the ATR 72 seats 74 passengers. Both aircraft are operated by a two person crew.
I hate flying American Eagle, they fly those shit ATR 72's. I swear those things are such a piece of shit, next time we'll fly Air Tran to Freeport.

After the suspicions of an organization created by the Tigersharks in Northern Iran. The government started their attempt to find the organizations. Northern Iran were assumed to be infecting people, causing humans to become tigersharks. This turned out to be real, and the purpose of the organization was truly found. But, these Transformation Plants were not only in Iran, but also in Western Armenia and Georgia. After the people fully learned about this, they started a riot that is also known as "Anti-Tigershark Riot" or "ATR.” Hundreds of thousands of people went out against the tigersharks. The roads and streets were filled by embittered people trying to overthrow the tigersharks and stop them from causing terrible crimes, but the tigersharks’ answer to them was to start infecting these rioting people. Nobody actually expected this, as it was said to only be possible in these Transformation Plants, so everybody started to panic, and seeked shelters to save their lifes. The unlucky ones who got infected, lost their mind, ability to speak, understand anything and became one of the tigersharks that were acting like a demented form of Zombies. The people who got to safety, were scared and anxious. What if these freaks could get to them, what happens if they get infected? They understood that this world can't end like that, and a one of the military leaders that did escape the riots, was able to call the President, and they had only one idea to solve this scenario; a genocide
Yungbooty Riots: ATR. There were three major ATRs. The 5th, 6th, and 7th Riots were made up of The ATRs.

ATR is a low key gang formed in California by a bunch of fuck up teenagers. Basically they just fuck shit up and leave there mark and leave. ATR stands for Average Teen Rebellion. Their motto: "When all hope is lost, R E B E L." Pretty fucking dumb.
" You hear ATR broke into the abandon factory yesterday."
"Shit, that's cool. They leave anything?"
"Just a nice paint job."
