Insomnia that occurs the day before your birthday. In the morning before your birthday tomorrow, you start to feel excited on the inside but not on the outside. In the nighttime, when you try to go to sleep you can't because tomorrow is your birthday and you stay up late that's where birthday insomnia mainly comes into play.
I can't sleep.
Why?
Because tomorrow is my birthday and when I try to go to sleep my body lets me stay up late.
Then you must have birthday insomnia.

A poop that requires no toilet paper afterwards due to the fact that it left nothing behind on your behind.
Dude, I was just taking a shit and realized there was no toilet paper. Luckily it was a birthday dump, or I would have been in big trouble.

A rock band from Toronto, Canada. A truly remarkable blend of fantasy and horror. While one might use words like "metal," "goth," or even "powerpop" to describe such a sound, "dreamy" and "surreal" do the band far more justice. It's a sound so uniquely visual, you might describe it more like a painting or a feeling. It's as if the story of David Fincher's "Seven" appeared like "Alice in Wonderland," but everything was a creamy shade of violet.
