From the moment that I saw you

Yeah it had to be love

Girl I can't help but adore you

Knew you'd fit me like a glove

What a life we have in store to

Spend together and stuff

You're a beauty, what a cutie

It's undoubtedly love

It's undoubtedly love.

My legs are going weak

And my heart's beating fast

I'm knowing I should speak to her

But I'm unsure what to ask

I feel like my technique

Might not be up to the task

But she's the love that I do seek

And hey, she's got a nice ass.

And when she looks at me I hope she'll feel the same

Due to the hormone that's released inside her brain.

Dopamine, dopamine.

It's a catecholamine neurotransmitter

Which means it sends a message in your brain

To tell you that you think that girl you're looking at is fitter

To make offspring with than any other dame

And when she looks at me, yes I can feel it beating

I can tell from the shortness of my breath

That my body has reacted to our wandering eyes meeting

And the high I'm on's comparable to meth

But methamphetamine's a drug of which I'm clean

Though I can't say the same of dopamine.

Dopamine, dopamine.

But dopamine's just one half of the tale

The chemical that get's you in the mood

There's another guy that you'll need to prevail

If you want to see a partner in the nude.

Dopamine is useless without norepinephrine

Focusing your efforts on one girl

Telling you that she's the one who's making your head spin

If this were an oyster then she'd be the pearl.

And so I lock eyes with this girl

Ready for our love to unfurl

I just want to curl up to her

But she's looking at me like she's ready to hurl.

I guess this lady doesn't feel the same

I thought there was a spark, but it didn't light the flame

But I still have the urge to ask her name

But that's not me, that's the hormone in my brain.

Dopamine, dopamine, dopamine, dopamine

And don't forget, norepinephrine, norepinephrine

Dopamine's best friend, norepinephrine, norepinephrine norepinephrine!.

From the moment that I saw her

Yeah I knew it was love

Couldn't help but adore her

Thought she'd fit me like a glove

But it turned out that my thoughts were

Just impulses, not enough

To get this beauty's pretty booty

It's just chemical love

It's just chemical love.
