The closest one can come to not caring, but still giving enough of a damn to give a flying fuck.
Dude1: Hey let's go fishing!

Dude2: No, I'm not norwegian...

Dude1: Who gives a flying fuck?

This is the day that the truth will be heard. We have all been wanting to say it, and say it loud. Let your lying , using , slut whore, frumpy Ex girlfriend know........it’s National no one gives a flying fuck about your crush day
Hey Frumpy, you realize it’s National no one gives a flying fuck about your crush day? So take that silver scat home, and clean his litter box. It’s smells like your breath.

It is to emphasize the word "fuck." It comes from the shorter version of "give a fuck" and then "give a flying fuck." It means "I don't care" but with emphasis. So it is an emphatic "I don't care!" Or also, emphatic "I could care less."
"I don't give a flying dog fuck if you want to go to the beach, we are NOT going!"

"I don't give a flying dog fuck if you like driving, I am doing the driving!"
