Not being a career gamer I feel I am missing large swaths of what seems like common knowledge about the games lingo. I left of when "fragged" was the hot new game slang. Shard & Engram are a few things I feel I should know but don't. Frustrating little in the way of in-game codex. Call it sad, but I make sure to have my phone close by to google new made-up words so I can follow what the heck is going on. Live and learn (or get fragged).
