Children. Single folks, you know what I'm talking about.

Daybreaker

Something that helps those long 8 hour days staring at a computer screen working on that WENUS report.

A video, news article or traveling gypsy show outside your office that makes the day tolerable by giving you a few minutes requiring no concentration what so ever. Baby Boomers used to have a daybreaker at the water cooler talking about their golf game and some dude's ugly kid.

Dude, I was just about to zone out when my BFF sent me this awesome daybreaker link to a pygmy and a rollercoaster.

Every now and then, I search the web for a daybreaker to wake up the staff. Best yet was some guy suing BMW for the motorcycle seat giving him a 20 month woody.

deal breaker 

An issue within a relationship that constitutes one partner breaking up with the other. Note that they do not need to be a "good" reason by society's standards, but are specific and individual to each relationship.

I can't believe he broke up with her because she didn't put out after 10 dates. I guess to him, that was a "deal breaker".
