[Intro]
[Verse 1]
Big communication, tell me what you want
Translate your vibration, let your body talk to me
Baby love, if you wanna show me what
You've been schemin' up, if you wanna (Let go)
Trust the simulation, don't you let it break
Every stimulation, promise I can take
What you wanna give? Boy, you better show me what
You've been schemin' up
[Pre-Chorus]

It's so good, it's so good

So good when we slow gravity, so good
It's so good, it's so good
Breathe one, two, three, take all of me, so good

Pass your boy the heatwave , recreate the sun
Take me to the feeling , boy, you know the one
Kiss it when you're done, man, this shit is so much fun

You got my heartbeat (Heartbeat) racin' (Racin')
My body blazin'

It's so good, it's so good
It's so good, it's so good
A reference to the warm feeling created after huffing poppers, which could in turn be referred to as a heatwave in a bottle.
Sivan is describing how a lover’s touch can feel “addictive.” This can be a direct reference to a drug experience, or simply to our body’s release of oxytocin that takes place when in the presence of a lover. Oxytocin is the drug that is often referred to as the “love drug,” as its function is to soothe and releases positive feelings.
Poppers, such as Rush, cause a decrease in blood pressure and an increase in heart rate, sometimes leading to tachycardia. His connection with this guy is affecting him like using poppers.
Troye Sivan is in the middle of an “action,” and is feeling the heat of the moment.
The lyric is confirmed to be an allusion to the popper brand Rush. Poppers are a liquid drug, that can make the user euphoric for a short period of time by inhaling it. It’s a popular drug in the gay community, as it can help them have a more pleasant experience during intercourse.

Troy refers to sniffing poppers, which is used to relax muscles prior to anal sex (take all of me)
Considering the tone of this entire song being founded in gay sex; this lyrics could be taken as a wordplay, where Troye really meant to say big cock but instead subverts expectations to say big communication,
leaving the hint there.
Possibly a reference to LGBT club classic I Feel Love by Donna Summer,
“Ooh, it’s so good, it’s so good
It’s so good, it’s so good, it’s so good”
Poppers also cause flushing and heat sensations in the body, similar to poppers, this boy has him feeling hot.
a slang term for a penis
A possible reference to the chorus of Carly Rae Jepsen’s Run Away With Me, which has similar thematic links to the passion and adrenaline of a new relationship:
Baby
Take me to the feeling
I’ll be your sinner in secret
When the lights go out
Run away with me
Run away with me
