When working in a Huhtamaki America's Mill, a person who stacks plates on any machine other than B-13 while it is running FRANKA, or any person who has never packed the afformentioned FRANKA 4 cup carrier. The Stacker Bitch will be known as such until he/she has done the said job, and also will be punished by back seat car rides until he/she has done the job. A Stacker Bitch is a human Pinata, so bash away when you see one!
Me: Jon is such a Stacker Bitch!
Drew: I know, He's been on B-14 all day. Make that stacker bitch ride in the back!
Me: Consider it done!
