I'm familiar with the term "porkies" to mean lies, which comes from "pork pies" which rhymes with "lies." Complicated! I came across the term "Beecham" to refer to photographs (photographic stills to stills to Beecham's pills to Beecham) and wondered about other clever rhyming slang terms. Is there a way to learn rhyming slang outside of rote memorization? It's not terribly useful in the modern age, but it is pretty fun.
