Hype in this case means that a character is indicated or even outright said to be strong, without us ever seeing any proof about this supposed strength.

Take Bacchus as an example: We were told he was equal to Erza so we expected that he'd easily defeat Elfman and Ichiya, because he was "hyped". But once we got to see his power, it turned out that it was less than what we were led to believe, since he lost to both.

Or Mirajane. We heard several times how strong and fearsome the "Demon" Mirajane was, but never got to see any feats to back that up until the fighting festival arc. She too was "hyped" without evidence. In her case though, it turned out that the hype was true, since she really was strong and fearsome.
