From the Frank Zappa, meaning an airheaded or naive girl or woman-nice to look at but without substance or intelligence.
There is a blonde at work who is tasty to look at but is a real Suzy Creamcheese. Nothing but sack-fodder.
Name invented by 1960s rock group Mothers of Invention for a particular underage groupie shared by several members of the group during a concert stop on Maui in 1966; referred to in several later songs. Alleged actual name Wanda Adams; see Rolling Stone, 1971 interview of Frank Zappa.
"Oooh, Suzy Creamcheese, you feel so fine!"
