Surface Forms

Morphology

piss + in + someone's + cornflakes

The literal image — someone urinating in another person's cornflakes — directly communicates the idea of ruining or spoiling that person's enjoyment, so a learner who knows 'piss', 'in', 'someone's' and 'cornflakes' can readily infer the metaphorical meaning. Although informal and vulgar, the mapping from the literal constituents to the figurative sense is straightforward rather than arbitrary.

Etymology

The idiom piss in someone's cornflakes comes from a rude image: imagine someone pouring piss into another person's bowl of cornflakes, ruining their breakfast. That's why it now means 'to spoil someone's enjoyment' or 'to ruin someone's fun'.
