your mom's box 

The last thing to be said before one leaves or exits for what may be the final time; famous last words.

IE: If you are radio DJ's leaving work on Friday not knowing if you will be back because one of your on air contests went awry in a Church, the last thing they say as their shift ends is, "Your mom's box."
