"Is he H to the izz-O, M to the izz-O?" (Nas – Stillmatic (Freestyle)) | accepted

There’s never been any proof that Jay-Z is homosexual, but “the gay rapper” (as if there could only be one!) was a persistent rumour at the time of this song. And Jay-Z was the rapper most often connected with it (others included Erick Sermon and Q-Tip). All unsubstantiated rubbish of course, but definitely a widely known rumour. And that rumour is what Nas is referring to here.

Don Dada is a Jamaican phrase, popularised by Super Cat’s tune of the same name. This song’s popularity in the US led to Super Cat working with several Hip Hop artists, including Biggie.

"Black kids got a craving for Cris" (Raekwon – Glaciers of Ice) | accepted

I’m not getting grapes at all here. It’s either cribs or Cris (as in Cristal). I think Cris makes more sense.
