A random varient of the Your Mom dis.  Don't actually use it in a real fight since you'll most likely get your sorry ass laughed at.  Use it more with sarcasm or jokes around friends.

Get the your mom in a boxmug. 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."
