"T.N.R. 250" — An abbreviation for "The Nouveau Riche 250" or Facebook's first 250 employees who became millionaires after the company's IPO.
"Bootcamp" — A six-week introduction to Facebook that all new employees must go through. Once they "graduate" bootcamp, new hires choose their teams.
"Faceversary" — The yearly celebration of how long an employee has worked at the company. The campus store sells special "Faceversary" balloons. It's even listed on employees' Facebook pages like a birthday to remind everyone to congratulate each other.

"Game day" — This is basically a grown-up version of field day. Each spring, Facebook employees band together in teams, dress in bright colors, and head over to a local park to face off in a series of competitions.

"Livin' the Dream" — Not a slogan, but another cafe on campus. Facebook renamed one of its cafeterias in memory of one of its first chefs, Josef Desimone, who was killed in a motorcycle accident in 2013.

Little Red Book" — Not to be confused with a little black book, Facebook gave out little red books to employees in 2012 when the company hit a billion users (now it's at the number, daily). While it uses Bootcamp to instill a bit of culture, the book contains Facebook's mission statements and a chronology of funny company moments. The last page challenges employees: "If we don't create something that kills Facebook, someone else will.
"20" — Although Facebook's newest campus was designed by Frank Gehry, it didn't get a special moniker to match its creativity. Instead, the social network company just named it "20" in a naming scheme similar to the buildings that make up the rest of its Menlo Park campus. 20 (pictured below with the rest of the campus in the background) has a green roof employees can use and its own set of cafeterias, microkitchens and conference rooms. Employees can bike or take a shuttle between 20 and the rest of campus.
"Gravity Room" — The aptly-named Gravity room totally ignores gravity in one section of Instagram's offices.
