A term coined by west coast Hip-Hop artist Anilyst. His song Triple Threat, which recieved over 7 million hits on youtube, is the first song to demonstrate "Syllable Sliding"…he describes it as "a form of rap that is more elaborate than the average way of rhyming….it’s the ability to rhyme each and every syllable in a bar with the other syllables in the next bar while still having it make sense and be clear, and while projecting subliminal messages and endless metaphors. This is Syllable Sliding.” He even rightfully named his first album "Syllable Sliding Vol. 1".
