You're lipsynching along to the Spice Girls song "Goodbye" while acting out the song as if you're in the video, and you somehow know all the words and harmonies.
I switched over to "Viva Forever". Now that's rock bottom. Remember the video for that song? It was so cool... little pixies. haha.
Yeah...never watched that. But back to the topic at hand... What does it mean if you do that every night?
