When you do something sneaky and get away with it. // when you do some trickery or pull some shit off.// when you pull off a pimp flip or parquet move or some athletic feat.
I went home with this bomb from the club last night and woke up to her mom showing up calling her name, so I flexed my NINJA MUSCLE, jump out of the window dipped down the fire escape and ran out.

Get the Ninja muscle mug.,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! "

Get the Selfie Ninja mug.When someone is passed out so hard dropping a steaming pile on their chest wouldn't wake them up. You get a fan blowing on them on high. The you rub one out standing behind the fan, and spooge so it gets blown all over them through the fan, which hopefully belongs to them.
