Bad moon on the rise 

(n.) -- the unfortunate view you get when a girl sitting in front of you is wearing very low shorts and a g-string or a thong.
Bad Moon On The Rise is actually a song title, but it fits this phenomenon because the "moon" refers to the girl's rear end, and the whole phrase implies that it's not a generally pleasant thing to look at.

"Ew, look at that girl!"
"Total bad moon on the rise."

Freezing Moon 

Everything here is so cold
Everything here is so dark
I remember it as from a dream
In the corner of this time

Diabolic shapes float by
Out from the dark
I remember it was here I died
By following the freezing moon

It's night again, night you beautiful
I please my hunger on living humans
Night of hunger, follow it's call
Follow the freezing moon

Darkness is growing, the eternity opens
The cemetery lights up again
As in ancient times
Fallen souls, die behind my steps
By following the freezing moon, yeah
