Lyrics:

I'm loyal, I'm faithful, I trust you
Then Friday, I walk in and bust you
With someone else

Stop me if you've heard this before
Stop me, stop me
Stop me if you've heard this before
Stop me, stop me

I'm wary of lasting relations
Since you started taking vacations
With all my friends

Stop me if you've heard this before
Stop me, stop me
Stop me if you've heard this before
Stop me, stop me

I know what you do
I know what you're up to
I know what you do
I know what you're up to

I lie here, I'm waiting, debating
I know you, you're out there, gyrating
With someone else
