It's a song, you
sex-obsessed idiots! A perfectly innocent Owl City song about a
guy who misses his girlfriend (or perhaps even a platonic friend, it isn't clear). Stop trying to turn it into something dirty.
When he uses the term, "Vanilla
Twilight", he is literally talking about the color of the sky:
I'll find repose in new ways
Though I haven't slept in two days
'Cause
cold nostalgia chills me to the bone
But drenched in vanilla
twilight
I'll sit on the front porch all night
Waist
deep in thought because when
I think of you I don't feel so alone
