A meme jumped out by a modern ignoramus child puffed by garbage media
BTW, have you noticed the pun is stated as born in 2010 because the stupid modern custom of searching on Internet only?
Actually, this pun was well known when I was a child…
And the meaning is totally different!
It is related to the fact hedgehogs copulates in the doggy style, but the female has many quills on the back, that are lowered just when the lady is “easy”
So males prick often their selves in the “parti nobili” (Italian polite form with the meaning of essential nuts ) before they can even start doing the job, and each prick is a vocalization that mimes a continuous flutter
A further meaning is that, because it’s such a “hard job”, when they succeed they come in a flutter as nobody else
