Nicki references the classic tongue-twister “Peter Piper” — which, in the context of this song, brings entirely different meanings to “tongue-twister” and “pipe.”

“Shag” is British slang for “fuck” (possibly a shout out to her alter-ego Roman, who is a Brit)

Pete Sampras is a famous tennis player whose professional heyday was during the 90s.

Jay-Z used to sell drugs on (high school) campuses. He even admitted in Decoded that he once got arrested but the cops ended up letting him go — he owns fake rappers like he did those police officers.

In taking his life, Florence will finally be able to let go of all the emotional baggage that she carries (the implication being that she’s still in love with him).

But now you ask “but she hates his guts, how can she still be in love?”

The opposite of love isn’t hate, it’s indifference.
– Elie Wiesel

Florence reminds her lover that the same devils of human nature reside within him as well (and maybe these led him to wrong her in the first place).

This could be a literal death or a metaphysical one — either Florence loses her life in the quest for vengeance or her identity as a person will “die” and be changed as a result of her quest

Possibly a reference to the Seven Deadly Sins: wrath, greed, sloth, pride, lust, envy, and gluttony. It was a combination of these seven devils (with wrath, pride and lust doing most of the legwork) that festered within Florence and eventually convinced her to seek vengeance.

It sounds like Florence plans to torch this shit with Greek Fire…or more likely it’s a boast that her rage is so great nothing could calm her down

There’s no recompense, no apologies, no bargains, no offers of power and no negotiations. Only by taking your life will Florence gain the satisfaction she seeks.
