Morphology

drop + a + bollock

The meaning 'to make a serious or embarrassing mistake' is not predictably derived from the literal parts 'drop' + 'a' + 'bollock' (a testicle); the image of 'dropping a testicle' does not compositionally map onto the notion of committing an error. This is colloquial British slang and idiomatic/metaphorical usage rather than a transparent compound, so learners who know the individual words would still not reliably infer the MWE's meaning.

Etymology

The idiom drop a bollock may come from a rude picture: imagine drop and bollock — 'bollock' was an old word for a small round thing or a part of the body, so to drop it feels clumsy and very embarrassing. That's why the phrase means 'to make a serious or embarrassing mistake'.
