abbv. for Name definitions here on UD.
If someone defines someones name, it a name def, or ND.
Very common to def someones name in a defamatory way, like "shaun - the cheapest MF ever, cheats on everybody....", or in a good way: "Brad - the cutes guy ever..."
A name def is considered by UDitors to be a good reason NOT to publish a def, or to remove.
Uditor 1: I found a defamatory name def, so I removed it.
UDitor 2: Yeah, I got several, both positive and negative, and didn't publish them.
