What does Brain Salad Surgery mean? Is it slang?
Yes. This is slang for fellatio, i.e., oral sex with a man. If you
look closely at the Giger painting of the woman on the inside of the
cover of the Brain Salad Surgery album, you may notice a "ghost" of
the head of a penis on her neck.
When asked what Brain Salad Surgery meant on the radio show "Rockline"
in 1992, Keith Emerson jokingly replied:
"Er, it means the same thing as 'Whip Some Skull On Me.' I don't know
what that means. Do you know what that means?"
