Aliasing Snakedick and Snake_Cock to Snake_Penis
Reason: These tags mean the same thing, and neither of the first two use 'Penis', which most of the site is standardized on. Mostly this is a trope of the Living_Gasm_Drive, but it could conceivably be used elsewhere, and maybe it already is. Those searches have a few things hidden under my blacklist.
Snake_Penis may not be the ideal term. To avoid confusion, perhaps it should be 'Penis_Snake' instead? In any case, to clean up these tags and make the database more consistent, they should be unified somehow.
