When the scene of a shart is left unattended over an extended period of time the
sharticles, or particles of shart begin to
harden due atmospheric exposure.
This results in
the shart forming a thin crusty lining in the jocks which although uncomfortable, is sometimes preferable to admitting to having performed the initial shart in the first place.
"I knew I should have changed after that shart. Now I've got
hardening of the sharteries."
"
Madeline is walking a bit
gingerly today, maybe she's got hardening of the sharteries..."
