Functional composition: "op"

In America, at least, when pronouncing f o g (the composition of
functions f and g), we say "eff op gee" (right?). That is, we
read the composition operator as "op." Does anyone know the source of
this? Perhaps this is an abbreviation of f "operating on" g. And
what is the history of this convention, do you know?
