Some kid at Dublin Jerome that keeps taking shits and then smears it on the the wall of the stalls. The suspect also shoves shit in the hand dryers so when you turn them on they shoot crap all over the place. On top of that they put the crap in the TP holder so you get shit on on your hands when you reach to get some. This person will probably be eaten alive by Parking Lot Pete

The doctrine of trying to avoid being in the public part of a restroom at the same time as a co-worker emerging from a stall after taking a shit, thereby preserving the anonymity of the person you heard violently exploding in the stall next to you.

Typically working in first-in/first-out order, if you go the bathroom and notice that someone is already using a stall (as if anyone wouldn't notice that earthquake fart), you should politely wait in your stall until that person has exited the restroom before you exit your stall. This order can sometimes be disturbed by speed-shitters and reading-a-freaking-novel shitters. If you're just taking a leak, you do not have to wait.
MAIL GUY: I was dropping trou this morning when I heard someone detonate some serious explosive diarrhea in the stall next to me. I waited for him to wash his hands and leave so that he could have his shitter anonymity.

COPY GUY: I bet it was Ray--that guy eats so much crap he's destined for the brown deluge.

MAIL GUY: Thanks to my good pooping manners, we will never know, and he can keep his dignity.

Having the water in the toilet splash up and hit your ball sack and/or taint while taking a dump.
I ran in to the bathroom and dropped my pants just in time to unload a high pressure dump. If I didn't know better, I could have swore my dookie performed an epic cannonball from the high dive with the amount of Shitter Splatter I wiped off my sack.
