A beericade is any device used to block a lunchtime beer from view. It is used by pwned employees who are afraid a fellow co-worker will wander in, see them drinking a beer, and report them.
I had a beer lunch with Bagels today. He was afraid someone would see him drinking a Xingu, so he made a beericade out of the napkin holder.
