I think it was a joke about the "phobia" part in which he mistaken it ONLY as "fear of"... When you hear "phobia" that is the main part you think about after all....

Though, in truth phobia means "fear and/or great dislike of"... I think it was just a simple mistake on the meaning of the interpretation on the meaning of the suffix vs what the suffix actually means... As was it a joke... :/
