An Ack is a person with no common sense. An ack is usually a child with slight autism who acts as if they are more solid than the dicks that penetrate them. They also get extremely triggered on any game from Minecraft to Destiny, causing them to have breakdown and cry to their mother. Finally, they seem to have no control over their bowels and often shit themselves, causing every piece of clothing, not just underwear, to be covered in shit stains. In serious cases, an Ack will be unable to agree with anyone else causing everyone, even their own family, to know then as a little bitch.
