Defriending threshhold

I just defriended someone on Facebook for the first time. My standards for accepting a friend request are pretty low (i.e. Do I know who you are and not actively dislike you?), so perhaps it's surprising it took this long.

This is an individual who went to high school with me, but I barely ever talked to him. In addition to constant Farmville updates, during the past week he posted 13 different status updates regarding Tiger Woods, all containing the term "manwhore." Example: "[former friend] wonders if anyone knows how many manwhores it takes to screw in a lightbulb not counting Tiger Woods of course".

Good gravy. Anyway, I'm done with that.
