When a persons shits themselves due to no availible toilet resources. The sheer mass of shit combined with heat means the shit turns into a cement which not only cements your pants to your arse but the sheer weight means it feels like they are carrying cement.

Bill: Sorry, i'm carrying a little more weight down below and have a severe case of cement pants.
