There's over 600 posts tagged as humping, but I can't figure out why it exists.
It seems like a random mix of grinding, doggystyle, generic sex, etc. And it's mostly tagged for still images, where humping is only assumed instead of seen. Some might have speed_lines to indicate fast humping, but many of those would fit best under rough_sex.
I would've outright suggested invalidating or disambiguating it, if it weren't already aliased with hump (which might also get tagged for camels, judging by post #608015).
Is there any reason to keep this tag, or should it be sorted out and invalidated?
