cassidy for freestyles huh? well, i saw him try to freesyle on mtv and he tried to rhyme fiesta with professor and molestor. he was trying to do the thing where someone keeps giving him words and he tries to keep a flow and basically not stop, even between words, make a song, the only person who i have ever seen that did that good was eminem, and he got words like nastrodamous, and excramin, not bikini and fiesta like cassidy got.
