Question

i forgot to ask this person yesterday, so name tbd from period 1) what do ghosts say at a bad performance?

Explanation:

This appears to be a riddle or a joke - related question. The typical punchline for "What do ghosts say at a bad performance?" is a play on words. Ghosts are associated with "boo" (a sound they are thought to make), and a bad performance might make people "boo" (express disapproval). So the joke answer is likely "Boo - ring!" (a play on "boring" and the ghostly "boo").

The question is a joke/riddle. Ghosts are associated with "boo", and a bad performance is "boring", so the pun "Boo - ring!" combines these for the answer.

Answer:

Boo - ring!
