Crazy tic tac bounce!? | EVERYDAY MYSTERIES

Considering you say giving it downward kinetic energy would be cheating, I don't see how giving it rotational kinetic energy isn't cheating... If your definition of dropping is "letting it fall with all it's mechanical energy in the form of gravitational potential energy" (which seems logically intuitive), spinning it isn't dropping anymore. On the other hand, if your definition specifically includes "without any downward kinetic energy", that leaves throwing it any direction that isn't down to be dropping as well, which doesn't really feel like dropping.
