Harry Potter Hang over 

when you wake up in the morning after a midnight showing of Harry Potter with one or more of the following symptoms:

throbbing headache, intense excitement, need to talk to everyone about the movie, post-potter depression, and sore muscles from standing/sitting/lying down in line
and of course extreme sleepiness

Man, I don't know if I'll be able to go to school today, I have a Harry Potter Hang over.

Rachelle is falling asleep on her desk, yet she has a huge grin on her face and is trying to talk to me about the movie, yet Bria who hasn't yet seen the movie is telling her to be quiet. She must have a Harry Potter hang over.
