The term used whenever a dude named Chris, Christopher, Christian, Kris, or Kristof ends up not making it home for Christmas. Sometimes a Chrismiss happens multiple years in a row.
Chris told me yesterday over the phone on the 24th that he wasn't making it home again for Christmas. This is now the third time in a row so it's going to be another Chrismiss.
