In these lines Jack puns the word “Interest” in it’s first meaning he’s saying that if you borrow money from him paying it back this should occupy one’s time and thoughts and in the second sense he expects a fixed charge for borrowing the money.

This next line descibes the firarm’s appearance while alluding to the fact that the stereotypical stance with your hands down your pants doesn’t mean that he is holding his genitalia, rather he is holding his firearm there.

Jack starts by assuring listeners that while they are having a jovial time, him and Lil T are not participating in a Tea party, the tea party line is a double entendre while in one sense a tea party is a quaint quiet social gathering it also refers to the Tea Party movement who strictly adhere to the american constitution and who engage in non-violent protest http://en.wikipedia.org/wiki/Tea_Party_movement Jack is affirming he is not American or concerned with peaceful protest instead he likens his activities to a Rock and Heavy metal gathering then double entendre’s the Rock to the narcotic crack cocaine and the Heavy metal to a firearm.

Here Jack is describing himself as black and grumpy, to “screw” is slang and means to have an issue with something. Jack lastly describes himself as a black Victor Meldrew, Victor Meldrew is a fictional character from a BBC Sitcom titled One Foot in the Grave, this character epitomises the grumpy old man. http://www.youtube.com/watch?v=HmD2wkQkhnE

Jack uses the term phat http://www.thefreedictionary.com/phat in the slang sense which is a positive term to describe something, but then uses its phonetic brother fat metaphorically, he says his rhymes ain’t fat they’re obese leaving the listener to consider if fat as the slang phat is a positive what would obese as a slang be? he then uses a double entendre to describe, that a listener might have trouble trying to work them out, in one sense reiterating the difficulty people have in calculating his rhymes and in another sense saying his rhymes cannot lose thier metaphorical obesity through exercise.

Jack feels his lyrical powers are with him forever!

Here is another double entendre Jack describes him and rap as bonded by marriage by saying what he says has a “ring to it” in one sense describing a metaphorical union and in another simply saying what he says is interesting and attractive to the listener http://idioms.thefreedictionary.com/have+a+ring+to+it

Here Jack is saying he feels embarrassed for the people that can’t work his lyrics out and in what seems like a compliment to rapper Royce da 5,9 he feels, like Royce his competition, pale in comparison seem lacking in importance and quality, http://idioms.thefreedictionary.com/pale+in+comparison really he is refering to Eminem being Royce’s direct competition being visibly pale in comparison. http://www.youtube.com/watch?v=rJOsjP33nF4

What Jack is refering to in this first part is the news media who somehow manage to glorify your achievments and at the same time destroy them. The second part is an example of this, a drunken celebrity being robbed in amazemet that he was “eaten” a term used to describe being robbed. Jack then plays on the “eating” theme and asks how he should wash down his meal? The next part is a literalisation as well as a double entendre Oasis a soft drink famed and marketed for being “still” http://www.youtube.com/watch?v=ikEO4lz3hs4 on a shelf making it “on another level, still” a slang phrase used as a superbative.

This is a double entendre an Iron can be used to straighten out a wringled item of clothing with the steam it provides and a spray of water, what Jack is refering to is straightening out an individual with the “Iron” slang for a firearm by dealing with the situation directly “full steam ahead” with a little bit of “spray” slang for a burst of gun fire.
