JoJ is a mysterious product from HoH SiS Foundation Repair.
HoH SiS got the JoJ done right. JoJ is an extremely popular topic on Aeiou, because you should do it all over again. Do it fifteen times all over again. It is believed (though not proven), that JoJ HoH Sis is part of the Foundation and serves as containment recovery in addition to foundation repair.
