BlackBarrel 

To run into someone in a moment of BlackBerry blindness while walking and looking down at your BlackBerry, iPhone, or other handheld device.

I was walking down the hall in my cubicle farm, and this workaholic PDA-hole nearly BlackBarreled right into me.

Blackballing 

Covering the balls (testicle) and genital area in black paint. Also called greasing.

A punishment that railroad staff (Mechanics) used to give to guys that spray paint (graffiti) the trains from the outside.
They are told to drop the cans and strip naked. The genitals are spray painted with their graffiti cans and sometimes grease aswell.
They are kicked in the testicles by the staff and/ or told to kick each other "in the balls" and told to run either naked or with only the shoes on. Could be difficult to run at this point because their testicles are aching.

Guy1: Hear that?! They are blackballing some poor sods.
Guy2: What's that?!
Guy1: Haha Come.

Guy 1: You already black balled me. I'm begging you! Don't kick my balls i have a girlfriend!
Guy 2: Should have been fucking her then instead of giving us work! Do you know how much time it takes to clean this shit! Spread them legs! You had the balls to do this shit, suck it up.
Guy 1: Oooohh! My balls!
Guy 2: Now run, go ice them fuckers!
