A nice piece of ass characterized by an upside down triangle of light formed by a fit womans crotch and thighs allowing light to show through. Usually means one won't be dissapointed

The view obtained when you look at a womans ass from behind while she is wearing tight pants. If you can see daylight through the crotch of them, she's not overweight.
I watched Ann walk by today and noticed that she definitely has daylight.

A daylighter is a person who sheds "daylight" on information that is being hidden or skewed as part of a person or entity’s attempt to bring about a pre-ordained outcome. They talk about what they discover.

A daylighter shines light on data or facts that have not seen the “light of day” due to misinformation or withheld information by journalists, government officials, individuals, or corporations. When information is withheld or hidden or when misinformation is used to obtain a certain result, such as enhancing an image, avoiding negative consequences or appropriate punishment, or to produce a certain kind of behavior (spending money, voting a certain way, not questioning “accepted truth,” or to induce fear or otherwise unearned trust), it can be said to be “propaganda.” Daylighters are deep thinkers and analytical, and don’t accept data without documentation (footnotes) or doing significant investigation and fact-checking. Healthy skepticism is a necessary characteristic to be significantly qualified for daylighting.

Not all daylighters are whistleblowers, but all whistleblowers are daylighters. Some daylighters could be called full-time daylighters. Others are less able to spend the kind of time that it might take to shine a light on a particular set of propaganda, but they have a solid daylighter attitude and value system. They clearly qualify as members of the Daylighter Club!
“My friend, John, is a true daylighter. He just documented on his blog how many lies our county executive has been using to justify spending taxpayer money on unnecessary upgrades to computer systems to be done by a company owned by a close family member of the executive.”

Working on a paid project while being paid by an employer during the same hours. Usually an 8-5 job. But using ones energy on another paid project and not producing any valuable units for the primary employer.
Person A: I was daylighting, worked all day on my consulting website instead of doing work for my employer 'Z'.

Person B: Sounds like you just doubled your income, but is it ethical? What does employer 'Z' think about it?

Person A: Let me look up ethical on UD. I'll get back to you.
