When your trying to rhyme a word and you just can't find a word or phrase that rhymes with it. (A word that rhymes with hardly anything).
"I'm trying to start a rap about a thesaurus, but what rhymes with thesaurus? Porous?, for-us?, you are a whore-us? Man it such a borange".
"That's the last time I start a poem about disestablishmentarianism, it's just borange".
"WHAT THE FUCK RHYMES WITH ORANGE! IT'S JUST A MOTHER FUCKING BORANGE."
