A form of retard/idiot or when someone does something stupid, it originated in Saint Josephs College Weed Heads for 2 very autistic children. these people would make fun of these retards calling them Ijaaack with an autistic tint to there voices.
E.g If someone says whats 2 plus 2 you would respond come on Ijack .
