Morphology

thunder + mug

Knowing 'thunder' (storm sound) and 'mug' (drinking vessel) does not transparently yield the meaning 'chamber pot'; the compound's referent is idiomatic, historical/dialectal usage rather than a predictable composition of the parts. This sense is metaphorical/lexicalized and uncommon, so a B1 learner who knows the constituents but has not seen the expression would not be able to deduce its meaning.

Etymology

Thunder mug may come from a simple picture: people kept a small pot by the bed and when it was emptied outside at night it sometimes made a loud, thunder-like sound, so the pot was called a thunder mug. That's why thunder mug means 'a portable container kept in the bedroom for toilet use' before indoor plumbing.
