U Dum

U Dum is a game where you, the player, tries to get the attention of another player in a variety of ways. After gaining their attention, you immediately shout "U Dum!" However, the defending player may preemptively shout "U Dum" after you have gotten their attention, nullifying your initial attempt.

Todd: "Hey Blair, I learned something interesting about you this weekend."

Blair: "Really? What's that?"

Todd: "I learned that U Dum!"

UDumber

Noun: 1. A person who uses UD posts for personal vengence, not realizing it makes them look pitiful. 2. A person who posts their own name on UD, not realizing it makes them look like someone you want to avoid at all costs.

That UDumber put the name of the girl who dumped him on. Has he lost his mind?
