When a relative or obscure acquaintance posts a comment on your facebook wall.
Examples of a Wall Kill:
Aunt X on Niece X's wall:
So, I heard you're an Atheist. Isn't it a little hypocritical that an Atheist celebrates Christmas? Do you have a website or more information I could read?

Mom X on Son X's wall:
Jamie! Your New Year Party photos are nuts! Give me a call sometime.
