Morphology

lose + one's + cookies

The literal constituents ('lose' + 'one's' + 'cookies') would suggest misplacing baked goods, which does not transparently yield the meaning 'become very upset or frightened.' This is an informal idiomatic/slang use (not a regular compositional pattern like 'lose one's cool'), so a B1 learner who knows the words would not reliably predict the intended meaning.

Etymology

Lose one's cookies probably comes from the image of cookies in your stomach falling out when someone 'throws up'. Because people often feel sick or out of control when very scared or upset, the phrase came to mean 'to become very upset or frightened'.
