some kind of dessert

from the Times' Whit Stillman profile:

“I detest Parfit,” said Echikunwoke, with bred-in-the-bone conviction.

“I agree,” Gerwig replied.

“Cut!”

“What is Parfit?” Smith asked. “Some kind of dessert?”

Nobody, including the actors, had any idea what Parfit was. Or to put it properly, who Parfit was, for Parfit was not a dessert but the renowned ethicist and philosopher Derek Parfit, white-haired author of “Reasons and Persons,” whose vogue among academics Stillman found irksome.

“You want to do one more?” Smith said after a few takes.

“Sure.”

Persons unsure of their reasons fired a final volley at poor Parfit.
