pencil shit 

When you are taking a shit and it is long and narrow like a pencil. This is usually caused by having a tight anus.

I walked in to the stall to find a long narrow shit. Someone must have taken a pencil shit.....

mechanical pencil shit 

When you can't clean your anus after pooping no matter how many times you wipe. Usually a mechanical pencil shit is one that takes a long time to come out, so one begins to wipe prematurely before the whole poop has completely dislodged itself from the butt hole.

One's shit keeps refilling like a mechanical pencil: no matter how many times that one wipes, he can't get it clean.

This mechanical pencil shit took two rolls of toilet paper to wipe and I still haven't stopped shitting.
