Lyric discussion by HASHCAKES, 

I though it sounded like "I got an SMG & I got a K2 & the only thing that's missing is a bitch like you." instead of "I got an 'F' and a 'C' and I got a 'K' too and the only thing that's missing is a bitch like yoU."

SMG's & K2's are both guns..Either way it will still make sense..

An error occured.
