The act of getting assaulted by a person with a mental handicap.
I smacked that retarded kid, and he totally goober graped me! I still have a black eye.
An amazingly disgusting product that is both peanut butter and jelly conbined in one jar. It can be found at most American supermarkets.
Today I went to the store to get some goober grape, it tastes like shit but at least you only have to spread on one substance.
