The Message Is: There Is No Message

I am an animated adolescent
Who lives in a colorless suburb
My girlfriend is a mouse or a rat
I can never really tell which
She talks in smoke rings
Above the music our town makes
Every Christmas there is a sleepover
And the whole town argues over where
I usually just hope it’s not here
Because I feel ill in this gathering
Some rockstar said I have cancer
It’s localized in my tonsils
That I keep in a jar next to my bed
