What does "推し鯖" mean?


I was browsing stuff related to the game Fate Grand Order when I ran into the
word "推し鯖". There's an entire hashtag for it on twitter.

I've learned that 鯖 is slang for server. But what does 推し mean in this
instance? Dictionary says its "fan" or "supporter" of. Does this mean like an
unofficial "fan server"




推し鯖 means "(my) favorite servant(s)". 鯖【さば】 is usually slang for server (it's
"[ateji argot](https://japanese.stackexchange.com/a/44255/5010)"), but in FGO
it stands for
[servant](https://fategrandorder.fandom.com/wiki/Servant_List_by_ID). Here, 推し
is another recent slang word which means "favorite (idol/character)". 推し on
its own doesn't mean "supporter", but X推し can mean "fan/supporter/follower of
X". 推し originally means "recommending" or "pushing", and this meaning was
coined and popularized among [AKB48](https://en.wikipedia.org/wiki/AKB48) fans
10 years ago or so.
