A type of exercise. In the instance where one person is ordered to do 30 'shitlicks', he must then drop on his/her back and crunch into his/her
abdominal region as if performing self-fellatio on their 'asshole'. The unwavering rule of the shitlick is not take any regular breaths and presumably take on no tangible form.
The idea came from Nova Scotia in the late 1800's when
New Zealanders took to the seas and had to thwart off the the local fisherman to monopolize the agricultural industry, thus winning
the Cold War.
