Worthless merch that you’ll forget about and not even wear or use once you get them. You could also burn your money. Plus, who the hell wants to be seen in merch for fucking Urban Dictionary? That’s like wearing merch for 4chan or Reddit. It’s a complete waste of money. Don’t buy it at all costs.
Maxwell: I just bought this UD Merch, am I cool now?
John:How the fuck is that going to make people think you’re cool? Sometimes I just don’t understand you, Maxwell.

UD Troll:

Someone who abuses UrbanDictionary.com:

- By adding so-called 'definitions' that include the full names, screen names, or personal information of someone they either have a problem with, or are trying to impress.

- By adding so-called 'definitions' that are poorly worded, plagued with bad spelling and even worse grammar, and nonsense (and inside joke rubbish that only they (or very few) can comprehend.

- By adding so-called 'definitions' that are nothing more than cleverly (or not so cleverly) worded message board replies.

- By adding so-called 'definitions' that violate section V. (especially 10. stalk or flame another person by submitting content deemed inappropriate) of the TOS, or violate the TOS in any other way.

- By subjecting the general population of UrbanDictionary.com to 'definitions' that we have to request be 'removed'.
Just a few examples:

Joe Schmo:
---------
I hate Joe Schmo. We work together, and he steals my lunch and beats me up every chance he gets.

"Joe Schmo sucks. I hope he dies. He has AIM and his screen name is ****** so chat him up and tell him to die!"


Jane:
----
I LOVE JANE!! SHE'S THE BEST GF IN THE WHOLE WORLD!@#@$$$#%$^ OMGWTFBBQ!

"Jane, will you marry me?"

A cowardly piece of shit who anonymously decides what is worthy of inclusion in the urban dictionary.
The UD Editor rejected my submission with no explanation. A cursory read shows lots of inane references and inside jokes posted. Fuck you, Mr. UD Editor.
