the.com/custard pie

The original troll: a dessert whose highest calling is being thrown in someone's face.

means A sweet, egg-and-milk-based baked dessert with a soft, wobbly filling — best known not for being eaten but for being hurled at someone's face in slapstick comedy.

from Custard itself traces to Old French 'croustade,' a pie with a crust (from Latin 'crusta,' crust), which drifted in English to mean the soft baked filling rather than the pastry around it. The pie's other claim to fame came from early film comedy — silent-era slapstick found that nothing landed a laugh like a custard pie smacking a dignified face, and the gag became so iconic that 'custard pie' turned into shorthand for that whole genre of comic humiliation, independent of anyone actually eating one.
