Hipster or not?

Sorry Crispin, but it should be: "Your flies are undone."
@fazered: you're a disgrace to your English teacher. I demand that you raise this issue with him/her on Monday...

Just heard the entire English department at my old school did a mass suicide. I feel suitably ashamed. I used language as my plaything, treating it with contempt. I know now that bad grammar for comedic effect is still bad grammar.

I'm going to go straight from now on.
