Girl or guy who makes out with every guy or girl in one night.

Usually a drunk girl and at a party, but could be considered a guy. A girl who gets on every guy and makes out with them, but doesn't do anything else, hence they become makeout rainbows
Man shes such a makeout rainbow when shes drunk but who isn't?
