O'Brien isn’t that popular of a rapper so being on his grind isn’t new to him.

Also OB is from “Up North” in Canada where he’s more likely to ice skate than grind

If you know what money from Canada looks like then the name for OB’s “label” makes complete sense

OB O'Brien is signed to Toronto’s Frostbyte Media

Since OB is Canadian he knows french which is sticking with the stereotype theme since a stereotype for Canadians is that they speak/are french

Je m'appelle OB comment t'appelle tu in english means My name is OB, what’s your name?

This line implies that you will be able to accomplish great things (“win that cup,”) if you overcome the stereotypes talked about in the opening lines of the verse

There are very few white rappers/professional basketball players just as there has only been one black president and there aren’t many black professional hockey players.

The kid is passing his classes and playing sports

Ghost is taking back the things he bought his girl/what she bought herself with his money

If she doesn’t want to give him that ring (“rock on your finger”) then Ghost is going to take her whole finger including the ring

Its very rare to earn a “5 mic classic” rating from The Source (a mainly hip-hop magazine) so if anyone were to be good enough to earn a 5 mic rating they would have to be a freak

Even though Shad isn’t rich and his life has ups and downs his music/jams will still rock your body like a kidney stone which is essentially a rock in your body

Kidney stones also “pass through” your body so when Shad’s tunes pass through your ears they’ll also rock you

By green Shad means money

Continuing with the golf theme of the “I’ll own the masters like Tiger” line he is also using green as in the location of the pin on a single hole of the golf course

The back nine is referring to the last 9 out of the 18 holes of a golf course
