Basically a tank that does damage. Unlike actual tanks though, they don't have taunts, strong initiation abilities (like amumu) or various other abilities that are designed to help you protect your team. An actual tank's job is to initiate a fight and/or protect the dps characters on your team.
A tanky dps instead is designed to run in and kill the enemy dps and not care about who's hitting him. Generally the best characters for fighting a straight up 1v1 fight mid to late game.
