San Francisco and the whole Bay Area (beyond the 415) has no shortage of slang words. So, what happens when San Franciscans leave our cozy area? They may face some confusing conversations because many of these phrases and slang words make little or no sense outside the San Francisco Bay Area. Here are 8 of our favorites, words that you’ll totally understand if you’re from San Francisco.

  1. Karl

Mark Gunn/Flickr Karl the Fog is San Francisco’s great marine layer. What other city names their fog? And then often refers to the fog by name?! Karl’s importance is recognized by most locals. When Karl is out, the sun is gone and the city is in its chilly, natural habitat.

  1. The 415

  1. Tech Bro

  1. Slaps

Steve Rhodes/Flickr Slaps are fun, upbeat songs from the Bay Area, but used more generally as a term for any wonderful song. The crowd at this concert is definitely enjoying some slaps.

  1. Hella

Gwen/Flickr Hella originated in the San Francisco Bay Area, but has since spread to become slang among all of Northern California and beyond. In fact, hella was even added to the Oxford English Dictionary in 2002.

  1. June Gloom

Omar Barcena/Flickr June gloom describes the foggy nature of San Francisco summers. Mid-spring and fall in the city are usually sunny and enjoyable, but by June Karl the Fog rolls in, hiding the sun for weeks on end.

  1. Burners
