Forced rhyme is , "near-rhyme" meaning that such rhyme is dull and unimaginative, knack, wooden, stiff.
(Forced rhyme tends to make use of other rhyming devices like assonance and consonance, so it overlaps in many cases with the definition slant rhyme, but forced rhyme is a much broader and loosely-defined term that can be used to apply to any type of near-rhyme in the final syllables of a word)
