Hampering a political candidate's chances of winning an election by circulating compromising old photos of the candidate on the internet. The term is especially applicable to sexually suggestive photos.
The term is based on the 2010 congressional campaign of 28-year-old Virginia businesswoman Krystal Ball, who received negative publicity after photos of her sucking on a Halloween dildo during the 2007 holiday were unearthed.
Student 1: Hahaha. Ben's blog swears he's going to run for Congress in a few years. Quick, let's save some pictures so we can krystal ball him later!
(Student 2 logs onto Facebook and begins to save photos of their "friend").
