smoke bomb and ninja flip 

when used together they mean ugly girl and girl who is out of your league respectively. Used when you are at a bar and there is no girl there that you think you could have sex with. Thus, "the bar is full of smoke bombs and ninja flips."

Ninjabomb 

Similar to photobombing, to ninjabomb a picture is to intentionally posing behind other people, peeking over their shoulders, under their arms, and in open spaces in other people's photos, for a later surprise.

The difference between a sneaky photobomb and a ninjabomb lies in that the ninjabomber is dressed like a ninja (in ninja garb).

Drew: "dude, I'm looking through my camera, I don't think I have ANY normal pictures of you from our halloween party last night."
Stephen: "yeah, but you do have over 20 of me ninjabombing."
