Why?

I can point out a whole collection of really creepy kinks. This is just a word that is normally used for when two animals produce offspring, so let's use it for people shagging, makes it more animalistic.

I really don't see the problem with this one but if you want real kina to blink twenty times, look into vore or guro

I've known a few people who used "breeding" as a kink word and I'm like motherfuckers i raised four kids it's not a fucking kink, it's a lifelong occupation.
