Rebel XD spat an amazing 852 syllables in 42 seconds in 2007 to beat his own Guinness World Record for Fastest Rapper. While the feat is impressive, it's slightly dampened by the fact that it's literally impossible to understand anything this dude is saying. At this lightspeed rate Rebel sounds more like an auctioneer than a rapper. His cypher may have helped him climb to the top of the Guinness World Record books, but as of yet it hasn't translated into him climbing the Hot 100 charts. On the other hand, so-called fast rappers like Twista and Busta Rhymes might be able to learn a thing or two from this motor mouth spitter.
