"It's lame when people use the phrase "rappity rap" in a negative way, to downplay the skill and effort it takes to write multisyllabic rhymes/patterns/punchlines/etc. Usually the people who use the phrase "rappity rap" negatively to slight good rappers, are doing it to justify lazy non-technical wack rappers. I prefer "rappity rap" to lazy rappers that don't sound like they are trying."

the responses seem to think he was flat out saying "Rappity Rap is lame."
