A smacked retard that should never be online. Smacktards usually participate in such activities as blowing up his own team killing himself repeatedly etc. In real life smacktards conceal their nature but can easily be sniffed out with some lysol. If a smacktard is seen online he should be shot repeatedly in the head before he can do any damage.
"HEY SMACKTARD!!! (fired shots at head)"
"Yo smacktard you're on the BLUE team idiot!"
"Fuck we lost again. Let's go massacre the smacktard.It's his fault."

n. - A person that lacks intellegence and/or common sense, to the point of seeming to be mentally retarded, who is not actually a retard, thus making it socially acceptable to smack them as needed. This condition is currently commonly caused by exposure to online chat rooms, and was previously mostly caused by smack (heroin, not cocaine as suggested by other definitions, and part of the origin of the term, if not part of the current evolution.)
