When you and someone else both think something is the best thing since sliced bread, and you both are wrong.
You and your friend both think the new cereal is the best thing since sliced bread, and it's just sugar and corn syrup.
You and your mom both think the new phone is the best ever, but it breaks after one day.
You and your brother both think the same stupid video game is the best thing ever, but it's just a bunch of ads.
