Define Moon River Meaning

A wondahhful song from the movie Breakfast at Tiffanys:
Moon River
wider than a mile
i'm crossing you in style
someday
oh dream maker
you heart breaker
wherever you're going
i'm going your way
two drifters
off to see the world
theres such a lot of world
to see
we're after the same
rainbows end
waiting round the bend
my huckleberry friend
moon river and me

1. To moon a river.
2. A very very old song.

A cumshot right between the ass cheeks resulting in a flow of sperm right down the crack.

Unexpected finger up the Anus.
