Four Letter Word

What a nice surprise and have I spoilt your appetite?
And I told you once, I told you once
So let me tell you twice, I wanted to say

A toast to emotion
Raise your glasses high and turn them this way
A balance of hormones that makes you feel like no one else
Makes you just the sane

Here's to love, here's to hate
Here's to everything that makes me realise
This is a four letter word

Here's to fear, here's to fate
Here's to everything that makes me realise
This is a four letter word oh, oh, oh

It's coming loud and clear, God, I fancy you, my dear
Well, I might be wrong, I might be wrong
I might need glasses all along

My deepest emotion
Nothing more than a chemical equations
Symphonies of stimulants
Swimming 'round in a beating gland, nearly caused a traffic jam

Here's to love, here's to hate
Here's to everything that makes me realise
This is a four letter word

Here's to fear, here's to fate
Here's to everything that makes me realise
This is a four letter word

Here's to love, here's to hate
Here's to everything that makes me realise
This is a four letter word, oh, oh, oh
Oh, oh, oh, oh, oh, oh, oh, oh
