There are currently four tags with 50+ uses that are, as far as I can tell, very similar in use:

* Overflow
* Cum_overflow
* Cum_splatter
* Cum_explosion

Besides the use case issues (post #608502 should clearly not have cum_explosion) and some possible split (stuff like post #667296 should probably be split into a different set of tags that implicates leaking), I'm pretty all four of these should be aliased into a single tag.

Overflow sounds like it might get tagged for leaking, or just for overflowing baths and such.

Cum_explosion seems like an extreme version of cum_splatter, and probably could be implicated to it.

Dunno what to do with cum_overflow. Implicate to leaking?
