Metal?

Joy to the world while you're decking all the halls 
Ya better watch out or we'll kick you in the balls 
Here we come a-wassailing Feliz Navidad 
Grandma got run over by a reindeer fa-la-la 

Crush your balls with a sleigh 
Jingle bells in your face 

(Chorus) 
Jingle bell jingle bell jingle bell metal 
Fucking shit up with a double bass pedal 
Ring-a-ling hear them ring, jolly and brutal 
escape from this very merry medley is futile 

Dashing through the snow in a wintry wonderland 
The little drummer boy never really had a band 
Come all ye faithful in a manger heard on high 
Do you hear what i hear, silver bells, rum-pum-pum
