Getting assigned BS chores and assignments from your boss that he or she easily could've done themselves, but chose not to out of sheer laziness. Meanwhile they are surfing the internet shopping for the latest accessories for their guns. Origins link it to a manager that was famous for doing this to many subordinates; whose name was "MIKE".
"Man, I just got Miked into going up to the 23rd floor to reboot a printer. This is BS!!" "Can you go get me that TPS report I just printed. Thanks." (that was a rhetorical question)
