No dumping zone
The period of time in which something bad happens during which you cannot break up with your significant other.
My girlfriend's dad just died. Guess she's in the no dumping zone for a while.
Dump Zone
When a person defecates inside the box of a calzone or pizza, closes it, and labels it "dump zone" in a public area for others to open and discover.
GGZ created a dump zone in a DP Dough box at UCONN and left it in the freshmen dorm room.
