(spoken:)
He went away, and you hung around
And bothered me, every night
And when I wouldn't go out with you,
You said things that weren't very nice.
My boyfriend's back and you're gonna be in trouble
(Hey la, hey la, my boyfriend's back)
When you see him comin', better cut out on the double
(Hey la, hey la, my boyfriend's back)
You've been spreading lies that I was untrue
(Hey la, hey la, my boyfriend's back)
So look out now, cause he's comin' after you
(Hey la, hey la, my boyfriend's back)
(Hey, he knows that you've been tryin')
(And he knows that you've been lyin')
He's been gone for such a long time
(Hey la, hey la, my boyfriend's back)
Now he's back and things are real fine
(Hey la, hey la, my boyfriend's back)
You're gonna be sorry you were ever born
(Hey la, hey la, my boyfriend's back)
Cause he's kinda big and he's awful strong
(Hey la, hey la, my boyfriend's back)
(Hey, he knows I wasn't cheatin'
Now, you're gonna get a beatin')
What made you think he'd believe all your lies, wahoo... wahoo...
You're a big man now but he'll cut you down to size, wahoo... wahoo...
Wait and see!
My boyfriend's back, he's gonna save my reputation
(Hey la, hey la, my boyfriend's back)
If I were you I'd take a permanent vacation
(Hey la, hey la, my boyfriend's back)
Yeah, my boyfriend's back... (etc til fade)
