Lyrics:

Crazy is when I go off the rails
This is what you've done to me
No, crazy is how your lovin' makes me feel
This is what I always wanna be
I like it when a girl gets crazy in bed
Don't mess with a bitch who's crazy in the head
You do (you don't!) wanna be crazy
And you don't (you do!) wanna be 'crazy'
To clarify: yes, no on the crazy
We hope this helps!
