I originally decided to call my company Green Room Speakers because of its theater definition: From Wikipedia: A green room is a room in a theater, studio, or other public venue for the accommodation of performers or speakers when not required on the stage. In other words, the green room is a place for performers to prepare before they get on stage. Yet I recently learned that green room has a second definition. In surfing, the green room is the inside of a barrel that is produced by a wave.
Bump stocks are simple pieces of equipment that replace the stock of a rifle and add a small support step in front of the trigger. The shooter rests his finger on this step and pulls forward on the barrel or forward grip to press the trigger against his finger.
A stock market crash is often defined as a sharp dip in share prices of stocks listed on the stock exchanges. In parallel with various economic factors, a reason for stock market crashes is also due to panic and investing public's loss of confidence. Often, stock market crashes end speculative economic bubbles.
