A selfie bomb is when you take a picture of yourself when something random, funny, stupid, awesome, or amazing is occurring in the background and you then post it to a social media site.
For instance take a selfie bomb when:
Your friend is passed out drunk with a dick drawn on his face
Street protesters who use social media to create a facade of activism. More concerned with updating images of themselves at protests and rallies on social media than articulating the cause. Easily triggered, with a deer in headlights look, when debated, and clueless of how to achieve the political goals for which they are protesting.
,A person who takes a picture of a person taking a selfie. They can be anywhere when someone is taking a selfie. The person taking the selfie has no idea that they are being photographed by the ninja. This is not a photobomb---the ninja is not in the selfie, so position is key.
"Hey man, check out the hot piece of ace! Whoa, she's taking alot of selfies! I'll stand right here so she won't see me and take some pictures ! "
"Stand over there so she won't see you. You can be a selfie ninja! "
When a girl uses filters, special lighting, contours and highlights her face to take a selfie but those who know her and see her in person know she's ugly ass hell.
