earthtwerk 

Any earthquake below 5.0 on the Richter scale. Barely noticeable by Californians, hardly raises any attention by local news or social media.

4.7 is not an earthquake, it's an earthtwerk. Welcome to California!!!

Earthtwerk 

1) an earthquake large enough in magnitude, to make the walls of your house shake violently.

2) when the fat girl down the street decides to shake her ass resulting in #1

damn did you just feel the earthtwerk?
