According to the wiki, piledriver is both a wrestling move and a type of 69 position. However, the tag is frequently being used for various non-69 sex positions, more so than for the situations in the wiki definition, in fact. Some are simply mistaggings of folded as piledriver (e.g. post #3199023, post #3110695), but others involve upside-down positions that don't have any other tag right now, AFAIK (e.g. post #3423616, post #3194166, post #3172188, post #3301399).
Which of these, if any, do you think should be tagged piledriver? What should the wiki definition be? Should any new tags be created?
