one upper 

someone who always follows your story with a better one or has things that are waaaay nicer than yours and makes sure you know about it

me: Wanna see the car I just got? one upper: Sure! Yeah, it's nice and all, I'm going to get a Lexus when my boyfriend gets back.

one upper: Your husband's truck is really nice! My boyfriend will probably get one like this, probably newer though.

One time editor 

Lame-assed punks who sign up to be UD editors only to get their stupid definition published,but,after realizing the backlog of definitions ,they take the chicken shit way out and plead for other editors to publish it rather than putting in some time and helping out with the editing.

Some shit-for-brains one time editor was begging to get his girl friend's name published for an anniversary present. Last of the big spenders.
