Eleven p.m., rising up in the evenin’
Gotta be undead, gotta go down to business
Gotta grab my knife, gotta have vengeance
Slaughterin' everything, the blood is flowin'
Dyin' all around, everybody's perishin'
Gotta get down to Crystal Lake
Gotta catch my prey, I see my targets (My targets)

Slicin' in the jugular
Dicin' in the aorta
Gotta make my mind up
Which life can I take?

It's Friday the 13th, Friday the 13th
Gotta get down on Friday the 13th
I’m lookin' forward to the slaying, slaying
Friday the 13th, Friday the 13th
Gettin' down on Friday the 13th  
I’m lookin' forward to the slaying

Murderin', Murderin' (Chop)
Murderin', murderin' (Hack)
Fun, fun, fun, fun
Lookin' forward to the slaying

11:45, I’m chasin' on the camp trail
Huntin' so fast, I want them to die
Kill, kill, think about the kill
You know that you’re mine
I got you, you got caught
My prey is in my sight
I got you, you got caught
Now you’re dead

Slicin' in the jugular
Dicin' in the aorta
Gotta make my mind up
Which life can I take?

It's Friday the 13th, Friday the 13th
Gotta get down on Friday the 13th
I’m lookin' forward to the slaying, slaying
Friday the 13th, Friday the 13th
Gettin' down on Friday the 13th 
I’m lookin' forward to the slaying

Murderin', Murderin' (Chop)
Murderin', murderin' (Hack)
Fun, fun, fun, fun
Lookin' forward to the slaying

Yesterday was Thursday the 12th, Thursday the 12th
Today i-is Friday the 13th, Friday the 13th (Murderin')
I-I-I so excited
I so excited
I gonna have a massacre today

Tomorrow is Saturday the 14th
And Sunday the 15th comes after ... wards
I don't want this killing spree to end

J-V, Jason Vorhees
So slicin' in the jugular (In the jugular)
In the aorta (In the aorta)
I'm decapatatin', crushin' (Run, run)
Fast deaths, openin' veins
Wit' a machete up in my hand (Kill!)
(Die) Runnin' by is a teenage blonde in front of me
Make her wanna scream
Check my time, it's Friday the 13th, it's a killfest
I’m gonna have fun, c'mon, c'mon, y'all

It's Friday the 13th, Friday the 13th
Gotta get down on Friday the 13th
I’m lookin' forward to the slaying, slaying
Friday the 13th, Friday the 13th
Gettin' down on Friday the 13th 
I’m lookin' forward to the slaying

Murderin', Murderin' (Chop)
Murderin', murderin' (Hack)
Fun, fun, fun, fun
Lookin' forward to the slaying

It's Friday the 13th, Friday the 13th
Gotta get down on Friday the 13th

Lookin' forward to the slaying
