The occupant of the office closest to the bathroom, where people needing to take a crap have to wait until the occupant vacates the office, to avoid the embarassment of bathroom noises being overheard.
I shouldn't of eaten those chili-cheese fries last night, Kourtney, the Poopy Cube Keeper, never left his office, so I had to crap my pants. Curses, Pooply Cube Keeper, Curses!

When 69'ing in the traditional position (girl on top) a piece of shit (cubed shape only) falls directly from asshole of girl into the mouth of partner and swallowed by 'said' partner.
My breath stinks so bad I swear that girl I 69'ed last night must have dropped a "Cubber (cube-er)" in my mouth.
