as a piece of s***. The term, piece of s***, is derived from POSsum. Being

Possums are dubbed as a piece of s***.
"Hey check out that
old computer sitting there in that pile of trash.
Tis such a possum."
"So this (computer) is a breakdown (to be disassembled)? Well then, grab that possum by its tail (by the power cord) and
load it in the truck. :B"
