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."
