Looks like there's no butt_sumo tag yet; are there enough applicable posts to justify adding it?
@Bicorn feel free to make it. I made plenty of tags before and populated them over time. Though I don't know what sort of rules you'd need to set in the wiki for it to be usable for posts that aren't just ass-to-ass.

I think the competitive aspect is the key - the picture needs to give off the sense that they're fighting rather than just gently bumping bottoms. Also ass-to-ass also has pictures showing the characters side by side, while proper butt sumo requires them to face away from each other.
