Umtard 

In the world of online gaming, Umtard refers to a retarded player that resorts to insults, rage quitting, clone killing (power-leveling), complaining, camping, hacking, glitching and being an asshole in general. The origin of this word spawns from the game Rush Team 2, where two players by the names of Umnika and MrUmni displayed all of the above characteristics to the extreme.

That guy is such an Umtard!

Stop complaining about lag you Umtard!
LOL! Look at that Umtard. He rage quit.
