You go to your graduation party with your girlfriend, your last blowout before taking her on a eurotrip. But the guy on stage starts singing about how he's fucking her. And she joins him on stage as the crowd laughs at you.

SCOTTY DOESN'T KNOW

Scotty doesn't know that Fiona and me
Do it in my van every Sunday
She tells him she's in church but she doesn't go
Still she's on her knees and Scotty doesn't know

Oh, Scotty doesn't know
So don't tell Scotty
Scotty doesn't know
Scotty doesn't know
(So don't tell Scotty)

Fiona says she's out shopping
But she's under me
And I'm not stopping

'Cause Scotty doesn't know
Scotty doesn't know
Scotty doesn't know
Scotty doesn't know
So don't tell Scotty
Scotty doesn't know
Don't tell Scotty

I can't believe he's so trusting
While I'm right behind you thrusting
Fiona's got him on the phone
And she's trying not to moan
It's a three-way call and he knows nothing, nothing

Scotty doesn't know
Scotty doesn't know
Scotty doesn't know
So don't tell Scotty
'Cause Scotty doesn't know
Scotty doesn't know
So don't tell Scotty

We'll put on a show
Everyone will go
Scotty doesn't know
Scotty doesn't know
Scotty doesn't know

The parkin' lot, why not?
It's so cool when you're on top
His front lawn in the snow
Life is so hard 'cause Scotty doesn't know
Scotty doesn't know

I did her on his birthday

Scotty doesn't know
Scotty doesn't know
Scotty doesn't know
Scotty doesn't know
So don't tell Scotty
Scotty doesn't know!

Kind of a stupid one I knocked out. Dont take it too seriously folks. JLLM will change the lyrics a lot unfortunately.
