A reference to the 1988 comedy-horror film Beetlejuice. Saying the title character’s name 3 times would summon him

Royce seems to be mimicking homie / rival Lil Wayne’s shoutout in “Mr. Carter” – except Royce was unable to pull of the celestial double-entendre

Kwame Kilpatrick, the former mayor of Detroit, was sentenced to four months in jail after being indicted on ten felony counts (he’s also received a few more years for violating probation and battling newer corruption charges).

Some of the charges stemmed from a 2002 mansion party where he was attacked by his wife after being discovered with strippers and he was later accused of having an extramarital affair (“being a player.”) He was sentenced in late 2008, two and a half years after D12 member Proof was killed in Detroit (“right after Proof split”).

A “rider” is a list of backstage demands that the artist makes. Some bands are known for their outrageous riders (especially rock group Van Halen, who once requested M&M’s with all the brown ones removed, and famously trashed the room once they found brown ones). Mr. Porter requires four pounds of fried chicken and, in tribute to Van Halen (and possibly Eminem), red M&M’s flown in from North Carolina just to make it more demanding.

The Six-Million Dollar Man was a mid-70s television series about a man who was rebuilt as a cyborg following an air crash, giving rise to the famous line which has entered popular culture:

We can rebuild him… we have the technology!

Eminem’s resolve after getting out of his addiction that he mentions in the last three lines before these two has made him the strongest he’s ever felt, like a cyborg. What doesn’t kill you makes you stronger.

Alizé is a line of liqueurs. Mixing NyQuil (a sedative) with alcohol would cause a dangerous reaction that would cause Eminem to crash his motorcycle into the wall of Lincoln High School, where he dropped out of ninth grade

If how you act determines where you live…

Also a commonly used line, Kanye has featured a similar line in “You Ain’t Never Gotta Ask”

“They say your attitude determines your latitude, I’m high as a motherfucker, fly as a motherfucker”

Mr. Porter is basically calling you crazy.

“El pollo loco” means “the crazy chicken” in Spanish, and it is also a Mexican restuarant chain.
