Name-Dropper

This word has a dual definition:
1. A person on Urban Dictionary who submits a definition of his/her name and makes it the 'coolest' definition possible.
2. A person on Urban Dictionary who submits a definition of his/her enemies' name and makes it the 'worst' definition possible.

Bobbo: I really enjoy voting for words on Urban Dictionary, don't you?
Karen: Yeah, but there are so many name-droppers just writing their name and saying cool things about themselves. I want actual urban slang!
