Half rhyme
Extracted from the Wikipedia article Perfect and imperfect rhymes.
Hip hop and rap
Half rhyme is often used, along with assonance, in rap music. That can be used to avoid rhyming clichés (e.g., rhyming knowledge with college) or obvious rhymes and can give the writer greater freedom and flexibility in forming lines of verse. Additionally, some words have no perfect rhyme in English, necessitating the use of slant rhyme. The use of half rhyme may also enable the construction of longer multisyllabic rhymes than is otherwise possible.
