Fokker is a Dutch name (the Red Baron flew a Fokker biplane). The Dutch word fokker means "breeder," and the corresponding verb is fokken. Example: Ik fok honden means "I breed dogs."
A few years back, it was hip in some circles to refer to heterosexuals as "breeders."
Put these disparate facts together and you realize that we heteros are just a bunch of straight fokkers.
