As far as I remember, there was either an image or set of images made by someone on /a/ that had Saber on them as well as a list of arbitrary "rules" that you must follow, among which involved stuff like 'don't stream your anime', 'don't use VLC use mpc-hc', 'no dubs use subs' and other shit someone on /a/ would make fun of you for.
Another image had Rin on it and parodied this one, basically saying not to give a shit about what the other image said and to do what you wanted, and either called Fate a shit anime or called Saber a shit waifu somewhere.
I believe both of these images were on the /a/ recommended wiki but that seems to have been taken down at some point.
