Ninjabag 

To flip someone's backpack inside out, insert all the books/stuff back in it, zip it back up, and hide it somewhere. This is a great school prank to your friends.

John: Yo where's my bag?
Steve: Not sure, but Alex told me you got ninjabagged so good luck.

ninjafart 

Flatulence occurring in the presence of another or others that requires "hands-free" manipulation of the anal sphincter to expel the gas in silent undetectable manner.

I was having fun driving you guys to the ice fishing expedition until someone released a ninjafart. Too bad it was SBD, or it may have gone completely unnoticed.
