The act of being overly excited for something. Excited to the point of overreaction. A typical example would be when a person ducks or moves as if they are evading being shot while playing a first person shooter. In that case, it is obvious that they cannot really dodge the bullets, but they act it out nonetheless.
"Damn, this kid was so souped when was playing halo that he acted like he was really in the game."
One who has been owned/pwned in a video game. In this case, you might add another durka along with "d" at the end (similar to the -ed in owned). This word can be used to replaced owned/pwned and usually refers to a higher level of ownage.
