I believe Freddie wrote about it:
Dislocate your spine if you don't sign he says
I'll have you seeing double
Mesmerize you when he's tongue-tied
Simply with those eyes, ooh ooh ooh
Synchronize your minds and see
The beast within him rise
Don't look back
Don't look back
It's a rip-off
Flick of the wrist and you're dead baby
Blow him a kiss and you're mad, ooh ooh ooh ooh
Flick of the wrist - he'll eat your heart out
A dig in the ribs and then a kick in the head
He's taken an arm and taken a leg
All this time honey
Baby you've been had
Intoxicate your brain with what I'm saying
If not you'll lie in knee-deep trouble
Prostitute yourself he says
Castrate your human pride, ooh ooh ooh
Sacrifice your leisure days
Let me squeeze you till you've dried
