The state of being so slammed drunk that one no longer acts with the full cognitive capacity of a normally functioning human being. The act of getting slamtarded often directly results in nights of unmatched glory as well as epic stories. Side effects include but are not limited to: fun, embarrassment, painful mornings, inability to control the volume of one's voice, loss of ability to speak coherently, and, in extreme cases, waking up with a woman you could have sworn was about 150 pounds lighter last night.
Stated concisely: being so drunk that you have to hold onto the grass to keep from falling off the face of the earth.
I started hooking up with some broad last night in my friend's closet, but then she stopped and told me to tell her what her name was and I was so slamtarded I couldn't do it.
Somone who is smart yet retarded in a sense. Particularly, a person who is smatarded is only smart when intelligence is being called upon. Otherwise mainly random, stupid, mentally handicapped, dumbfounded, and ADD. Most of the time, unintelligent people cannot see through this type of person and assume that they really are just completely stupid, but on the inside the smatarded person is laughing at them because they are the lesser.
