On TV the other night they were talking about Gay Photo Bombing, a term I was not familiar with.
Photo Bombing is the fine art of ruining other people's photos, usually by running into the background or making a silly face, and is usually done to strangers.
Gay Photo Bombing refers to gay rights activists interfering with the signs and protests of people protesting exactly the opposite causes. And it is awesome.
These are some of my faves, and more can be found at http://tinyurl.com/38hqdko.
