bathroom ninja

A person who occupies a bathroom stall and refuses to make any BM noises until the entire bathroom has been vacated. Occasionally, a bathroom ninja will even go so far as to stand on the toilet seat to avoid detection by other bathroom-goers.

Jacob hid in the shadows cast by the stall walls like a bathroom ninja until the final shitter had left the restroom.

pulled a ninja

When someone appears or disappears from the surrounding area with few or no people noticing.

Also when you do a really cool ninja move, especially if you could never do it again.

Joe: Oh, hi Jon.
Jon: Hi Joe.
Sam: Hey guys!
Joe: When did you get here?
Jon: He pulled a ninja.

Man: *drops glass*
Waiter: *catches glass without spilling drink*
Man: Wow, you just pulled a ninja!

ninja ant

When one is running in the grass, on the blacktop, ect. and trips for no apparent reason which causes them to fall on their face.

I was playing football in my backyard and running in hot for a touchdown when suddenly at the 5 yard line damn ninja ants attacked me just before the victory.

ninja studying

when you pretend to be hard at work to get your mom off your back about homework, but you're really watching tv shows on hulu.

I was ninja studying last night. Learned everything off of bones and house. Think I'm ready for that biology test now!
