Fartin' around the turd is a figure of speech used to imply that somebody or
something is wasting time or
procrastinating.
This figure of speech comes from the actions of a gaseous individual, who instead of going to the bathroom and dropping a deuce, with just sit there and fart around the turd all
afternoon.
"
Hey Justin, quit fartin' around the turd, these are
open-air cubicles and it's starting to smell like raw sewage in here."
"Hey Joe, quit fartin around the turd and do your
taxes already."
