name def

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.

super def

short for super definitions

it's what you find when you're just casually looking up a word, but the definition is just way too fucking long, and you nearly get a cramp in your scroll finger just searching for the end of it.

there is a super def for just about every big celebrity or big
musician. for example look up Elvis Presely and you will be treated to multiple super defs. this is especially frusterating because the true definition for Elvis is just simply the king of rock n' roll. see? no super def needed.
