To 'Boff the Mcfly out of', meaning to have sex with a girl so vigorously as to hopefully rememedy her poor taste in music.
1. Man: "I'm seeing this cool girl man, but she listens to terrible music!"
Friend: "Take her home and Boff the Mcfly out of her!"
2. Man: "So what happened last night man, did you Boff the Mcfly??"
Friend: "I Boffed the Mcfly out of her then i popped my bag of wheat crunchies all over her face! ...it was fun times!"
