1. MCB
A Middle Cubicle Bandit. Someone who, in a public or workplace toilet environment with three cubicles, deliberately chooses to occupy the middle cubicle when either:

a) none of the side cubicles are occupied
b) one of the side cubicles is occupied and the other is vacant

A disgraceful and flagrant abuser of toilet etiquette who should be named and shamed.

It is common courtesy to choose the side cubicle as a first option and only ever use the middle cubicle in an emergency if the other two are occupied.

The real purpose of the middle cubicle is to provide a comfortable space between shitters.
I was just squeezing one out and that bloody MCB came in again. To make matters worse, he had a case of the shits and stunk the place out in quick time. Couldn't get out of there quickly enough.
