Get Up, Get Out! Lyrics

Why are you laughing as if you're my friend?
I'm gonna slap you again and again and again
I like you better when you go away
Gotta get up, gotta get out, gotta get up
You gotta go away
you were the love of my life for a day
I kind of thought that
You'd feel the same what...No way!
Consider you a figment of my imagination
But will you every go away?
