Not sure if you are just being sarcastic or not but
It’s from the movie Stripes.
Psycho
The name's Francis Sawyer, but everybody calls me Psycho. Any of you guys call me Francis, and I'll kill you.
Leon:
Ooooooh.
Psycho:
You just made the list, buddy. Also, I don't like no one touching my stuff. So just keep your meathooks off. If I catch any of you guys in my stuff, I'll kill you. And I don't like nobody touching me. Any of you touch me, and I'll kill you.
Sergeant Hulka:
Lighten up, Francis.
