Bob it up 

To screw something up beyond belief that seems like a sure thing, with no real excuse.

Example 1: Bob was driving his truck in a 1 sq. mile field with one single tree in it, and still managed to hit said tree head on. Totally bob it up.

Example 2: Bob was playing pool and a ball was sitting in a pocket, and he managed to miss the shot, and put the cue ball in fore mentioned pocket. What a way to bob it up.
