This is completley hypothetical, this situation does not exist for me. But lets say you know someone who you really don't like, as in you pretty much hate them and want them to fall off the face of the earth. You have an oppurtunity to [censored] their mother... How much of an exception are you willing to make in terms of her looks?
That would be too much..
YOu can perhaps get the "hated" guy screwed by a donkey or something
Or just find a nuke and vaporise him, why bother **** his mother or sister for that matter
this is mad.. to **** somebody's mother? eeeeewww... it's not the mother's fault anyway.. it's between u and that person, it's never between u and that person's mother anyway..
Just forget him.
Don't speak to him.
And get on with your life.
if you honestly hate this person that much, show/have the strength of your convictions and passion and take it up with him personally...leave the Mother and Sister out of it all together.
