double-dog-dump
When a dog takes a dump and another dog comes along and takes a dump right on top of it.
Oh no, I stepped in a double dog dump.
(While a double-dog-dump is extremely rare in nature, metaphorically it is quite common in humans; so that the second person can put all the blame for a bad deed on the first person.
