I'm the mudblood of Slytherin
Of the house with secrets held tight within
Of course, our head of house is Snape
The one whose black robes follow him like a cape
House before blood is what they say
Lest the reputation of Salazar decay
The liars the cunning and the killers
The ones whose lives would make good thrillers
We never get caught sneaking at night
By during the day all we do is fight
You call us dirty liars and cheaters
Just because we have the toughest of beaters
So I'm the mudblood Slytherin
Of the house with secrets held tight within
