This is a nod to mega film star Dwayne ‘The Rock’ Johnson. “D-Wayne” is a play on his first name Dwyane, while “Johnson” is a play on his surname—"johnson" is another word for penis.

In an interview with Noisey, Lovato revealed that two songs on Tell Me You Love Me are about someone they’re close to. Lovato hasn’t confirmed, but it’s speculated that both “Ruin The Friendship” and “Only Forever” are about their longtime friend Nick Jonas.

In the same interview, they touched on the songs and the person they’re about, who they discovered had also written a song about them:

I was frustrated with a certain situation. And I was like, ‘You know what, I’m just going to write about it.’ And so I did, and sent [the songs] to that person, and that was, interesting. Any time you send a song about the person, to the person—it’s ballsy. It’s like, ‘Hey! Here’s my feelings for you!’ … They knew [about my feelings], but neither of us had acknowledged [them] before. And then it turned out that person had written a song about me, and we exchanged songs. That person was like, ‘That’s an incredible song.’ And I was like, “Yeah, well. It’s like, ‘Hel-lo!’”

This is a nod to Toni Braxton’s 1993 song “Breathe Again.” The song is about the possibility of her breaking up with her boyfriend:

If I never feel you in my arms again
If I never feel your tender kiss again
If I never hear I love you now and then
Will I never make love to you once again
Please understand if love ends
Then I promise you, I promise you
That, that I shall never breathe again
Breathe again
Breathe again
That I shall never breathe again
Breathe again

In September 2017, Kendrick Lamar placed #6 on Forbes' annual highest paid hip-hop artists list, reportedly racking in over $30 million dollars in the past 12 months.

Given the fact he made $30 million dollars in one year, it’s likely that he really does have $64 million sitting in the bank.

“La Flame” is an alias of Travis'. On September 22 2017, TMZ reported that Kylie Jenner—Travis' girlfriend at the time—was pregnant with his child.

The TMZ report reads:

We’re told 20-year-old Kylie began telling friends earlier this month at the Day N Night Fest in Anaheim, CA.

Sources also say 25-year-old Travis Scott, Kylie’s boyfriend, has also been telling his friends. We’re even told – although we cannot verify – that he’s told friends they’re having a girl.

One source says Travis was at a recent event telling people about the pregnancy and how his life was going to change.

On February 6, 2018, Kylie announced via Instagram that she and Travis had given birth to a baby daughter, Stormi Webster.

Lean is a drink comprised of promethazine with codeine, soda (usually sprite or fanta), and candy (typically jolly ranchers) and originated in Travis' hometown of Houston, Texas.

Travis has mentioned substituting alcohol for lean on other songs, like “Tourist”:

On that lean and soda, I’m not no alcoholic

And “Ghosttown”:

We don’t want alcohol drinks, only soda and codeine

A “valet” is a personal attendant. The most well-known type of “valet” is a someone who parks your car.
