In addition to Kyle Shanahan's dense playbook, there's another thing that quarterback Jimmy Garoppolo should probably learn before the 2018 season starts.

Locals really, really don't like it when people use the phrase "San Fran."

"We just got in yesterday, me and my family, so we got a nice little dinner up in San Fran," Garoppolo said in a press conference on Friday to formally announce his $137.5 million, five-year contract.

Even though Garoppolo has lived in the Bay Area for less than a year, 49ers fans on Twitter were quick to remind their new quarterback that the only acceptable nicknames for San Francisco are "SF" or "The City."
