Last night I got served
A little bit much of that poison baby
And last night I did things
I'm not proud of and I got a little crazy
Last night I met a guy on the dance floor
And I let him call me baby

And I don't even know his last name
My mama would be so ashamed
It started off "Hey cutie where ya from"
And then it turned into "Oh no what have I done"
And I don't even know his last name
Wooo

We left the club, right around
3 o'clock in the morning
His Pinto sittin' there in the parking lot
Well it should've been a warning
I had no clue what I was gettin' into
So I'll blame it on the Cuervo
Oh where did my manners go?

And I don't even know his last name
My mama would be so ashamed
It started off "Hey cutie where ya from"
And then it turned into "Oh no what have I done"
And I don't even know his last name
Here we go

Today I woke up thinkin 'bout Elvis
Somewhere in Vegas
I'm not sure how I got here
Or how this ring on my left hand just appeared
Outta nowhere, I gotta go
Take the chips and the Pinto
And hit the road
They say "What happens here, stays here"
"All of this will disappear"
There's just one little problem

I don't even know my last name
My mama would be so ashamed
It started off "Hey cutie where ya from"
And then it turned into "Oh no what have I done"
And I don't even know my last name

What have I done?
What have I done?
What have I done?
Oh what have I done?
I don't even know my last name

Well it turned into "Oh no what I have I done"
And I don't even know my last name
Yeah yeah yeah
Woooo

Mmmm yeah, yeah, yeah, yeah, yeah, yeah
Ohhhhhhh

It started off "Hey cutie where ya from"
And then it turned into "Oh no what have I done"
And I don't even know my last name
Oh yeah
