A possum is
something at which
you would usually refer to as a
piece of s***. The term, piece of s***, is derived from POSsum. Being possums here in Texas are such nasty little rodents (well, they are in Houston =\), 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"
