Bratinee
An afternoon theatrical or cinema presentation, often around holiday times, marked by the conspicuous attendance of many small, loud children and their parents who don't seem to know when it's appropriate to remove a child from a theater.
I saw the "bratinee" of that show and I think the lead really nailed that song but I couldn't really tell what for all the screaming and crying and asking questions out loud and dropping cokes and SHHHHHHHH sounds.
