An old theatre tongue twister. Used as a way to warm up the tongue before a show, it has gained notoriety recently due to Cards Against Humanity, and it has been difficult to for people to say to this day.

1. An old theatre warmup that became such a notoriously difficult tongue-twister, that even Cards Against Humanity uses it as one of their cards.

2. A phrase to say whenever one of your friends is tongue-tied, to remind them just how bad at saying words in their own language they are.
Bailey cannot say A Box of Biscuits, A Box of Mixed Biscuits, and a Biscuit Mixer, let us all point and laugh!
