The act of shitting in a lunch box instead of making a healthy meal. Frequent occurrence on the Popular American Television show, "The Brady Bunch."
Peter Brady opened up his Scooby Doo Lunch box to the undeniable pungency of Alice's Lunch. He tossed the fetid pile at Buddy Hinton, who was just glad it wasn't a bowl of her famous hershey squirts. Alice was always had a couple of zingers ready, that was for sure.
