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."

Get the ATR mug.
A todo ritmo
In spanish, it means something like "To all rythm". It's an exclamation of approval.
- Eh vieja, se hace algo este finde?
- Seeh, hacemos una jodita en casa
- ATR wachín
