text: what started the mistletoe...? how/who/what started the mistletoe kissing tradition? frigg, a norse goddess, asked everything in the nine worlds not to kill her son, balder, who was doomed to a tragic death.  but she neglected to ask the mistletoe, because she thought it so harmless.  loki tricked hodr into killing his brother, balder, by throwing a branch of mistletoe through his body.  *  i couldn't find where it says how it became a kissing tradition.  but i heard it somewhere before, and it was something like: frigg thought it should never again be used for something so terrible, so everyone should hang it over their heads and kiss under it.
