I can see the potential ambiguity, but given that all the other cards and rules that mention giving are clear that you lose something at the same time, it's almost certainly the case that you lose a level and the lowest level munchkin gets one.

I'm also almost certain you give one level to the player with the lowest level that is not you. Bad Stuff is meant to be bad. The card doesn't say what to do in this case, so I could be wrong, but I don't know how you could give a level to yourself...
