[Verse 1]
Doctor, doctor, help
Another good boy down
Fever off the chart
One look and you fell

[Pre-Chorus]
So obsessed but this ain't love
Think you need some drugs
If you asked me what went wrong
Then I'd state

[Chorus]
Got a bad case of boy brain, case of boy brain
All the stupid shit that you say that don't make no sense
Insane, baby, insane, damn, that you think about me, running through your head
Maybe you think that you're in love
But it's been a week, like, what the fuck?
Boy brain, boy brain
Got a bad case, b-b-bad case of boy brain (B-b-boy brain)

[Verse 2]
Symptoms start to show
When you get too close
Prescribe a single dose
Of "Don't call me no more"

[Pre-Chorus]
So obsеssed but this ain't love
Think you need some drugs
If you askеd me what went wrong
Then I'd state
[Chorus]
Got a bad case of boy brain, case of boy brain
All the stupid shit that you say that don't make no sense
Insane, baby, insane, damn, that you think about me, running through your head
Maybe you think that you're in love
But it's been a week, like, what the fuck?
Boy brain, boy brain
Got a bad case, b-b-bad case of, case of boy brain (Boy brain)

[Outro]
Boy brain, b-boy brain
Boy brain, boy brain
La-la-la-la-la-la
Boy brain, boy brain
Boy brain, boy brain
Boy brain, boy brain
Got a bad case, b-bad case of boy brain
