I think he might be referring to the words themselves - 'rabbit' and 'pork' - in that, despite not rhyming, together they are nonetheless described as rhyming slang.

[lupire]

The rhyme is "pork" and "talk". In rhyming slang, the slang term rhymes with the original meaning word.

Example: "comment and post" for "eat toast".

Apples and pears: stairs

for example too (for a single word example)

It’s pork and talk, I can’t make them rhyme even with a Boston accent ( which could do “car park” and “talk”).

[zarzavat]

In my London accent “park” and “talk” do not rhyme completely. Park has the usual “ah” vowel, but talk has an “o” vowel (in southern England we would call this an “or” vowel but I suspect that might confuse you more).
