What does he birds and the bees mean?
“Reproduction” which is .. sex. Where exactly “the birds and the bees” originated nobody knows, but word sleuths William and Mary Morris hint that it may have been inspired by words like these from the poet Samuel Coleridge: “All nature seems at work … The bees are stirring–birds are on the wing … and I the while, the sole unbusy thing, not honey make, nor pair, nor build, nor sing.” Making honey, pairing … yes, we can definitely tell what Sam had on his mind. The Morrises offer the theory that schools in years past taught about sex by “telling how birds do it and how bees do it and trusting that the youngsters would get the message by indirection.” Right. Luckily for the perpetuation of the species, there’s always been Louie in the schoolyard to explain how things really worked. http://www.straightdope.
