A photo bomb. Is not a photo with explosive properties, no sir ! A photo bomb is the art of placing one’s self into a photo taking session without the knowledge of the other person.
Whether this is done intentional or not is subject to debate. However, a good photo bomber are those who slips in; poses funny and leaves. They leave behind in the background, their antics.
Just look at this photo, normal people would have deleted it. I found it funny and thus kept it.
Always Keep Fighting And Never Lose Hope
