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.
Earl: Hey Jim, did you get any last night?
Jim: Nah, Right when I was about to Tom came in and cock blocked me
Earl: Word? This is the 5 time this week.
Jim: I know, He's such a MCB
