Osterich style
A sexual postion - whilst a man is behind a woman standing and pushes her head against the wall. If an "accident" occurs and the females head goes through the wall and into the cavity of the wall frame and the man continues to have inter-course with her it is osterich style.
Mate : "man what the fuck was that bang in your room before and why does the chick have scratches all over her face???"

You : "Osterich style"
