The placenta is an organ that develops in the uterus during pregnancy. Although Biggie likely fucked pregnant women at various points throughout his life, this sexual boast shouldn’t be taken literally.

Trigger (1934-1965) was a golden palomino horse that was famously owned by Roy Rogers, the famous American singer and actor known for his portrayal of a cowboy in various radio, film, and television shows (especially The Roy Rogers Show)

Shaolin Island is a slang term used by members of Wu-Tang Clan to describe Staten Island in New York City. (c.f. Raekwon on “Can It Be All So Simple”)

“Touch something” is slang for pulling out his gun – Method Man uses the same term on “What the Bloodclot!?!” off his 1994 album Tical (released only a few months after Ready to Die)

Biggie is fond of tricolons (three parallel ideas in quick succession). This is also exhibited on:

“Going Back to Cali”

Going back to Cali, strictly for the weather
Women and the weed, sticky green

“Ready to Die”

Mic ripper, girl stripper, the Henny sipper

and “Dead Wrong”

Because you know I love it young, fresh and green
With no hair in between, know what I mean?

This line refers to English-Australian singer Olivia Newton-John’s 1981 hit single, “Physical.”

Biggie expresses similar disdain for martial arts in favour of being armed on “Things Done Changed” (using Kung-Fu as his example instead)

Boricua is a term Puerto Ricans often use to describe themselves, stemming from the island’s indigenous Taíno heritage (originally Boriken, meaning “land of the brave lords”).

Biggie was presumably familiar with Puerto Rican slang because of the significant population living in New York City – in the early 1990s, Puerto Ricans comprised 80% of the city’s hispanic population, and 12% of its total population.
