It seems that Pusha T prefers to used rental cars instead of actually owning one himself.

He mentions this inclination in regards of his choice of transportation for mainly two reasons. The first one being an opportunity to show off his considerable amount of money in a rather subtle manner.
Second, while he may actually have one car to his name, Pusha T uses rental cars only for the sake of riding dirty.

This hook levels criticism against other rappers who blindly hate and degrade rap music from the South i.e. 50 Cent) who, in an interview, named Southern Rap simplified.

It also is important take Pimp C’s and Bun B’s deep roots in South into consideration when trying to understand this set of mind. Because as Bun B stated in an interview with MTV the origins of UGK:

We dropped Too Hard to Swallow on February 21, 1992, and it sold, like, 40,000 copies in two and a half months, mostly in the Texas region. Lake Charles, Louisiana; Jackson, Mississippi; places in Texas — those were primarily the first cities to support us. Because we were small-town cats, we spoke from a small-town mentality, and a lot of the small-town people felt that and latched onto it immediately

Capo, der übrigens auch von Twitter Gebrauch macht, bezieht sich hier auf die Vorliebe anderer Rapper den Kurznachrichtendienst Twitter (zu dt. etwa Gezwitscher) zwecks Kommunikation zu verwenden, folglich zu twittern (dt. zwitschern). Verständlicherweise zeigt das Logo Twitters die Silhouette eines Vogel.

Weiterhin besteht die Möglichkeit, dass sich auf “Twitter-Beef”, zum Kofferwort “Tweef” umgeformt, bezogen wird, der darin besteht, dass zwei oder mehr Rapper sich auf verbale bzw. schriftliche Weise auseinandersetzen.

Spaceghostpurrp is referencing his strong preference for the colour in terms of clothing that also is spahred by his fellow members of the Raider Klan. He told Complex:

Black is my favorite color and it’s Raider Klan’s main color. We got three main colors in Raider Klan: red, black, and green, which are the colors of Africa. Black is our main color because black is a bold color. I should not have to wear black every day to prove that I’m a Raider but it’s a bold color and it represents me and what I am to date—a bold motherfucker that’s unknown and can’t be described.

A further continuation of the Pokemon themed line before. The slogan of the very famous Pokemon series is “Gotta catch ‘em all” therefore ASAP Ferg is referring for his insatiable hunger for more in every aspect the most likely being for either money or hoes.

This line can be understood in two different ways:

• ASAP Rocky refers to his profession as drug dealer and states that his turnover is quite high

• Along with Kanye West, ASAP Rocky is probably the best known fashion aficionado in the hip hop world and is famous for wearing rather artisanal outfits and has influenced current street wear trends. Thus ASAP Rocky refers to the fact that many people try imitate his style and purchase the same designer pieces he does.

Kweli ensures his wife and the audience that his consumption of marijuana is a habit he can easily cast off.
This line may also suggest that he deals with a lot of problems in life.

His wife wants him to quit getting high as she opines it to be irresponsible but its Talib’s only escape from life and the things he think are wrong and things he cant stand in life.
