He called it San Fran at the founder dinner, and everyone immediately knew he had just moved here.

01Origin

There is no identified coiner of "San Fran." It appears to have developed as an obvious shortening of San Francisco, but unlike SF or The City, it never became broadly accepted local speech. The outsider test was established well before the current tech scene: KQED condemned the name in 2010, and The Bold Italic later described it as outside the local vernacular and liable to set off alarm bells.

The taboo subsequently became part of transplant and tech-culture humor. It appears in an SF Tech Bro Purity Test as something insiders criticize, while tech entrepreneur Greg Isenberg used "San Fran" to illustrate that a young programmer from Nebraska had never visited the city and did not know local conventions. In 2024, state senator Scott Wiener amplified the joke by demanding that the California DMV stop printing "San Fran" on residents' driver's licenses.
