Every entry gives the literal reading, what the meme really means, where it came from — and an honest note on when using it makes you sound dated.
A meme is the hardest part of a language to look up. Dictionaries list words; nobody lists the joke that a word has turned into. These entries are written for someone who speaks no Chinese at all — including, in every case, a warning about whether using it now makes you sound like you learned it from a list.
Everything here is original writing, not copied from an encyclopedia. Entries cover the meaning, the origin, a comparison to something you already know, and what happens if you use it in the wrong room.
