Leather Goddesses of Phobos is an interactive fiction video game written by Steve Meretzky and published by Infocom in 1986.

Joel Berez spotted the added line before anyone else arrived and erased it quickly, but the name stuck and was jokingly brought up whenever a non-existent game title needed to be worked into a sentence.

Upper management was more difficult to convince, and then-CEO Al Vezza (who was more interested in the business side of the company) was not enthused with the idea.

"[4] In The Status Line (formerly The New Zork Times), Infocom's official newsletter, Steve Meretzky stated that the title Leather Goddesses of Phobos was conceived more than four years before the game was released.

"[4] Meretzky states that the "naughtiness" levels were based on the film rating system, with tame, suggestive, and lewd corresponding to G, PG, and R respectively.

[7] .Info in 1987 gave the Commodore 64 version four stars out of five, describing it as "fun to play, though Infocom has produced more challenging standard-level text adventures ... a lot of giggles in this one".

[9] A sequel to Leather Goddesses of Phobos, subtitled Gas Pump Girls Meet the Pulsating Inconvenience from Planet X!, was published by Activision in 1992.

In the 2015 film The Martian starring Matt Damon, Leather Goddesses of Phobos was referenced as being loaded on fellow astronaut Beth Johanssen's laptop alongside Zork II.
