What's up with the wigglecock tag? The page says "anatomically correct prehensile [cetacean/kangaroo] cock", but urban legend aside, those are _not_ prehensile (and most kangaroos' cocks are bifurcated, to boot).

From what I can tell, the tag is intended to mean something between prehensile penis and tapering penis; should it be replaced with those tags as appropriate?

Guess I'll go ahead, then.
