We let her in on secret meetings
She held the secret in her hard little hands
We'd never guessed she'd be a snitch
Little did we know, deception was her plan
I wasn't sorry to say that purple pustules hurt
Spelling words of betrayal on her face
I know it might sound harsh
She won't forget, 'cause we left scars
She's a sneak, Marietta's a sneak
Maybe she'll see what's important in the end
Maybe she'll learn how to be a better friend
Marietta's a sneak, oh, Marietta's a sneak
We let her in on DA meetings
She learned the true Defence Against Dark Arts
But if I see that witch again
I might just blow her perfect little world apart
Oh, Marietta, how could you deceive us?
We even showed you your Patronus
I know it might sound harsh
We won't forget, 'cause we left scars
She's a sneak, Marietta's a sneak
Maybe she'll see what's important in the end
Maybe she'll learn how to be a better friend
Marietta's a sneak, oh, Marietta's a sneak
I know that purple pustules hurt (She's a sneak)
I know that purple pustules hurt (She's a sneak)
I know that purple pustules hurt (She's a sneak)
And Marietta's a sneak
I know that purple pustules hurt (She's a sneak)
I know that purple pustules hurt (She's a sneak)
I know that purple pustules hurt (She's a sneak)
Oh, Marietta's a sneak
I know that purple pustules hurt (She's a sneak)
I know that purple pustules hurt (She's a sneak)
I know that purple pustules hurt (She's a sneak)
Oh, Marietta's a sneak
I know that purple pustules hurt (She's a sneak)
I know that purple pustules hurt (She's a sneak)
I know that purple pustules hurt (She's a sneak)
And Marietta's a sneak
