If you want to have fun with someone who is
pedantic about these things, do what I do and call it by a more correct name:
Centrifugal Effect.
Nine times out of ten the person you used this term on will begin their
rant about there being
no such thing as centrifugal force anyway.
Occasionally,
what you actually said will dawn on him or her during the rant, but you will more often have to to interrupt the rant and point it out.
Interrupting a rant makes me feel all warm and mooshey inside.
