Shadow Bum 

A homeless person that lurks in the shadows, normally in alleyways, and appears seemingly out of nowhere to ask for change or other items.

Shadow Bums can appear day or night, but mainly strike when you think the area is free of homeless.

"I checked around for bums and everything. I thought the area was clear, but then out popped a shadow bum from behind the building and he asked me for a cigarette!"

Shadow Bumping 

When on an online car game your player is at a delay causing your car to hit other players when you didn't hit them or you hit a car that isn't there anymore.

Man, this game has so much shadow bumping. I keep hitting players!

Shadow-bumping 

On the IMDB forums, the act of posting a blank response and then deleting it a second later thus intentively bumping the targetted thread and remaining anonymous as the bumper.
Specifically detested because it is a stealth form of necroposting and often used by trolls.

boxOmetal: some idiot just revived that y2k thread
cardboardboy: yes, well done idiot
boxOmetal: wtf?
cardboardboy: saw your name on the most recent post before it was deleted you shadow-bumping idiot

Shadow Bumper 

Terminology used to typically describe a caucasian male who has the innate ability to move in on the female lovers of black men and successfully steal them away. Such a man is often blessed with a particularly charismatic swagger, uncompromising tenacity, advanced sexual skill and perhaps most importantly a penis so epic in proportion that it often easily out-impresses any Afrocentric competiton.

Person 1: "Check it out, it only took cracka a week to turn that ho out."

Person 2: "Fuckin' shadow bumper!"
