Aliasing ss13 → space_station_13
Link to alias
Reason:
Space Station 13, a roleplaying videogame, is often abbreviated to 'SS13' by everyone who doesn't feel like or is unable to type out the full name. The game is what comes up when you google SS13, if you don't believe me.
EDIT: The tag alias ss13 -> space_station_13 (forum #254888) has been approved by @NotMeNotYou.
