This is four rappers running a clinic on threat delivery. Each verse is a different style of dominance: EST Gee stays cold and factual, 42 Dugg moves like he's bored by the violence, Rylo Rodriguez gets granular with the lifestyle details, and Lil Baby closes it out sounding untouchable. The song title references temperature but the actual temperature is how calm they all sound while describing chaos.
Overkill drill, spin at the building the wake at / I'd be on what I'm on if I ain't rap
The wake line is the coldest thing here. He is saying they would show up to the funeral to finish what they started. Then he pivots to say rap didn't change him, it just gave him a microphone. The detachment is the scary part.
Since y'all niggas apes, I don't mind killin' monkeys
This sounds like a punchline until you realize it is not a joke. He is using wordplay to say murder does not bother him if he sees you as less than human. The casual tone makes it land harder than if he was yelling.
Last night, I fucked a booster, woke up, text everybody size / Played plain janes, but now I'm goin' bustdowns
Rylo gives you the texture of the life. He is dating someone who steals clothes for a living, so he texts his crew their sizes the next morning. This is not bragging about wealth, it is showing how the hustle runs through everything, even pillow talk.
Way before coronavirus, I had them youngins masked up / I got twenty million cash now and still ain't near enough
Baby timestamps his violence, then admits the money does not fix anything. That second line admits what most rap songs won't: accumulation does not end the feeling that made you start accumulating. He sounds successful and unsatisfied at the same time.
Like I ain't the one who started this shit / Like I don't make sure them lawyers paid and them charges dismissed
He is frustrated people are forgetting he built the infrastructure. Paying lawyers is as much part of running the operation as anything else. The 'like I ain't' phrasing shows he feels underappreciated for keeping everyone out of prison, which might be the realest complaint on the whole track.
The song works because nobody is trying to convince you. EST Gee sounds like he is reading a list. 42 Dugg sounds distracted. Rylo gives you inventory. Lil Baby sounds tired of being famous. Four different tones, same message: this is just what we do, whether you believe it or not.
