A piece can have multiple meanings from just being used an abbreviation/short name for something e.g. you piece of shit! to anything more generalised e.g. nice piece!
The term Molepiece brings these two majestic meanings together allowing the instigator of said word full artistic license over it's meaning. It can be used most commonly in the workplace to avoid finding oneself in an angry boss situation or inevitable HR incident.
