What is the meaning of the song “You had me at hello”?

You had me at hello by A Day To Remember.

Lyrics:

I’m missing you so much, I’ll see you die tonight

Just so I can get to you before the sun will rise

I know the signs are on and I feel this too

None of that ever seems to matter when I’m holding you

And I’m wasting away, away from you

And I’m wasting away, away from you

What have I gotten into this time around

I know that I had sworn I’d never trust

anyone again but I didn’t have to

You had me at hello.

I’ve never seen a smile that can light the room like yours

It’s simply radiant, I feel more with everyday that goes by

I watch the clock to make my timing just right

Would it be okay?

Would it be okay if I took your breath away?

And I’m wasting away, away from you.

And I’m wasting away, away from you.

What have I gotten into this time around

I know that I had sworn I’d never trust

anyone again but I didn’t have to

You had me at hello

You gave me butterflies at the mailbox (you had me at hello)

You gave me butterflies at the mailbox (you had me at hello)

You gave me butterflies at the mailbox (you had me at hello)

You gave me butterflies at the mailbox (you had me at hello)

You gave me butterflies (you are so cute)

at the mailbox (you had me at hello)

[x4]

What have I gotten into this time around

I know that I had sworn I’d never trust

anyone again but I didn’t have to

You had me at hello

You had me at hello

You had me at hello
