clang association

Clang associations are ideas that are related only by similar or rhyming sounds rather than actual meaning.

A disturbed man in the back seat was shouting constantly, using clang associations (phrases that rhyme but make no sense) and an abundance of four-letter words.

He stated that as a young man he was heavily influenced by James Joyce and Flann O'Brien, particularly his wordplay, obscure words and references, metaphors, irony, parody, paradox, symbols, free associations, clang associations, non-sequiturs, and sense of the ridiculous.
